[7.x] Convert most OSS plugins from integTest to [yaml | java]RestTest or internalClusterTest (#59444) (#60343)
For all OSS plugins (except repository-* and discovery-*) integTest
task is now a no-op and all of the tests are now executed via a test,
yamlRestTest, javaRestTest, or internalClusterTest.

This commit does NOT convert the discovery-* and repository-* since they
are bit more complex then the rest of tests and this PR is large enough.
Those plugins will be addressed in a future PR(s).

This commit also fixes a minor issue that did not copy the rest api
for projects that only had YAML TEST tests.

Rename MetaData to Metadata in all of the places (#54519)
This is a simple naming change PR, to fix the fact that "metadata" is a
single English word, and for too long we have not followed general
naming conventions for it. We are also not consistent about it, for
example, METADATA instead of META_DATA if we were trying to be
consistent with MetaData (although METADATA is correct when considered
in the context of "metadata"). This was a simple find and replace across
the code base, only taking a few minutes to fix this naming issue
forever.

Christoph Büscher 9a9ee9abed [Docs] Add example to reimplement stempel analyzer (#42676)
Adding an example of how to re-implement the polish stempel analyzer
in case a user want to modify or extend it. In order for the analyzer to be
able to use polish stopwords, also registering a polish_stop filter for the
stempel plugin.

Default include_type_name to false in the yml test harness. (#38058)
This PR removes the temporary change we made to the yml test harness in #37285
to automatically set `include_type_name` to `true` in index creation requests
if it's not already specified. This is possible now that the vast majority of
index creation requests were updated to be typeless in #37611. A few additional
tests also needed updating here.

Additionally, this PR updates the test harness to set `include_type_name` to
`false` in index creation requests when communicating with 6.x nodes. This
mirrors the logic added in #37611 to allow for typeless document write requests
in test set-up code. With this update in place, we can remove many references
to `include_type_name: false` from the yml tests.

Removes typed calls from YAML REST tests (#37611)
This PR attempts to remove all typed calls from our YAML REST tests. The PR adds include_type_name: false to create index requests that use a mapping and also to put mapping requests. It also removes _type from index requests where they haven't already been removed. The PR ignores tests named *_with_types.yml since this are specifically testing typed API behaviour.

The change also includes changing the test harness to add the type _doc to index, update, get and bulk requests that do not specify the document type when the test is running against a mixed 7.x/6.x cluster.

Make hits.total an object in the search response (#35849)
This commit changes the format of the `hits.total` in the search response to be an object with
a `value` and a `relation`. The `value` indicates the number of hits that match the query and the
`relation` indicates whether the number is accurate (in which case the relation is equals to `eq`)
or a lower bound of the total (in which case it is equals to `gte`).
This change also adds a parameter called `rest_total_hits_as_int` that can be used in the
search APIs to opt out from this change (retrieve the total hits as a number in the rest response).
Note that currently all search responses are accurate (`track_total_hits: true`) or they don't contain
`hits.total` (`track_total_hits: true`). We'll add a way to get a lower bound of the total hits in a
follow up (to allow numbers to be passed to `track_total_hits`).

Remove the single argument Environment constructor (#27235)
Only tests should use the single argument Environment constructor.  To
enforce this the single arg Environment constructor has been replaced with
a test framework factory method.

Production code (beyond initial Bootstrap) should always use the same
Environment object that Node.getEnvironment() returns.  This Environment
is also available via dependency injection.

Nik Everett bb06d8ec4f Allow plugins to build pre-configured token filters (#24223)
This changes the way we register pre-configured token filters so that
plugins can declare them and starts to move all of the pre-configured
token filters out of core. It doesn't finish the job because doing
so would make the change unreviewably large. So this PR includes
a shim that keeps the "old" way of registering pre-configured token
filters around.

The Lowercase token filter is special because there is a "special"
interaction between it and the lowercase tokenizer. I'm not sure
exactly what to do about it so for now I'm leaving it alone with
the intent of figuring out what to do with it in a followup.

This also renames these pre-configured token filters from
"pre-built" to "pre-configured" because that seemed like a more
descriptive name.

This is a part of #23658

Nik Everett caf376c8af Start building analysis-common module (#23614)
Start moving built in analysis components into the new analysis-common
module. The goal of this project is:
1. Remove core's dependency on lucene-analyzers-common.jar which should
shrink the dependencies for transport client and high level rest client.
2. Prove that analysis plugins can do all the "built in" things by moving all
"built in" behavior to a plugin.
3. Force tests not to depend on any oddball analyzer behavior. If tests
need anything more than the standard analyzer they can use the mock
analyzer provided by Lucene's test infrastructure.

Ryan Ernst 212f24aa27 Tests: Clean up rest test file handling (#21392)
This change simplifies how the rest test runner finds test files and
removes all leniency.  Previously multiple prefixes and suffixes would
be tried, and tests could exist inside or outside of the classpath,
although outside of the classpath never quite worked. Now only classpath
tests are supported, and only one resource prefix is supported,
`/rest-api-spec/tests`.

Throw error when skip or do sections are malformed, such as they don't start with the proper token (START_OBJECT). That signals bad indentation, which would be ignored otherwise.

removes the remnants of that multiplexing support.

Simon Willnauer fe1803c957 Remove AnalysisService and reduce it to a simple name to analyzer mapping (#20627)
Today we hold on to all possible tokenizers, tokenfilters etc. when we create
an index service on a node. This was mainly done to allow the `_analyze` API to
directly access all these primitive. We fixed this in #19827 and can now get rid of
the AnalysisService entirely and replace it with a simple map like class. This
ensures we don't create a gazillion long living objects that are entirely useless since
they are never used in most of the indices. Also those objects might consume a considerable
amount of memory since they might load stopwords or synonyms etc.

Nik Everett 9270e8b22b Rename client yaml test infrastructure
This makes it obvious that these tests are for running the client yaml
suites. Now that there are other ways of running tests using the REST
client against a running cluster we can't go on calling the shared
client yaml tests "REST tests". They are rest tests, but they aren't
**the** rest tests.

Nik Everett a95d4f4ee7 Add Location header and improve REST testing
This adds a header that looks like `Location: /test/test/1` to the
response for the index/create/update API. The requirement for the header
comes from https://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html

https://tools.ietf.org/html/rfc7231#section-7.1.2 claims that relative
URIs are OK. So we use an absolute path which should resolve to the
appropriate location.

Closes #19079

This makes large changes to our rest test infrastructure, allowing us
to write junit tests that test a running cluster via the rest client.
It does this by splitting ESRestTestCase into two classes:
* ESRestTestCase is the superclass of all tests that use the rest client
to interact with a running cluster.
* ESClientYamlSuiteTestCase is the superclass of all tests that use the
rest client to run the yaml tests. These tests are shared across all
official clients, thus the `ClientYamlSuite` part of the name.

Ali Beyad 19d0dbcd17 Removes waiting for yellow cluster health upon index (#19460)
creation in the REST tests, as we no longer need it due
to index creation now waiting for active shard copies
before returning (by default, it waits for the primary of
each shard, which is the same as ensuring yellow health).

Nik Everett 71b95fb63c Switch analysis from push to pull
Instead of plugins calling `registerTokenizer` to extend the analyzer
they now instead have to implement `AnalysisPlugin` and override
`getTokenizer`. This lines up extending plugins in with extending
scripts. This allows `AnalysisModule` to construct the `AnalysisRegistry`
immediately as part of its constructor which makes testing anslysis
much simpler.

This also moves the default analysis configuration into `AnalysisModule`
which is how search is setup.

Like `ScriptModule`, `AnalysisModule` no longer extends `AbstractModule`.
Instead it is only responsible for building `AnslysisRegistry`. We still
bind `AnalysisRegistry` but we only do so in `Node`. This is means it
is available at module construction time so we slowly remove the need to
bind it in guice.

Ryan Ernst a4503c2aed Plugins: Remove name() and description() from api
In 2.0 we added plugin descriptors which require defining a name and
description for the plugin. However, we still have name() and
description() which must be overriden from the Plugin class. This still
exists for classpath plugins. But classpath plugins are mainly for
tests, and even then, referring to classpath plugins with their class is
a better idea. This change removes name() and description(), replacing
the name for classpath plugins with the full class name.

Simon Willnauer e91a141233 Prevent index level setting from being configured on a node level
Today we allow to set all kinds of index level settings on the node level which
is error prone and difficult to get right in a consistent manner.
For instance if some analyzers are setup in a yaml config file some nodes might
not have these analyzers and then index creation fails.

Nevertheless, this change allows some selected settings to be specified on a node level
for instance:
 * `index.codec` which is used in a hot/cold node architecture and it's value is really per node or per index
 * `index.store.fs.fs_lock` which is also dependent on the filesystem a node uses

All other index level setting must be specified on the index level. For existing clusters the index must be closed
and all settings must be updated via the API on each of the indices.

Adrien Grand eef19be072 Deprecate string in favor of text/keyword. #16877
This commit removes the ability to use string fields on indices created on or
after 5.0. Dynamic mappings now generate text fields by default for strings
but there are plans to also add a sub keyword field (in a future PR).

Most of the changes in this commit are just about replacing string with
keyword or text. Some tests have been removed because they existed because of
corner cases of string mappings like setting ignore-above on a text field or
enabling term vectors on a keyword field which are now impossible.

The plan is to remove strings entirely in 6.0.

Boaz Leskes 2a137b5548 Make index uuid available in Index, ShardRouting & ShardId
In the early days Elasticsearch used to use the index name as the index identity. Around 1.0.0 we introduced a unique index uuid which is stored in the index setting. Since then we used that uuid in a few places but it is by far not the main identifier when working with indices, partially because it's not always readily available in all places.

This PR start to make a move in the direction of using uuids instead of name by making sure that the uuid is available on the Index class (currently just a wrapper around the name) and as such also available via ShardRouting and ShardId.

Note that this is by no means an attempt to do the right thing with the uuid in all places. In almost all places it falls back to the name based comparison that was done before. It is meant as a first step towards slowly improving the situation.

Ryan Ernst ef4f0a8699 Test: Make rest test framework accept http directly for the test cluster
The rest test framework, because it used to be tightly integrated with
ESIntegTestCase, currently expects the addresses for the test cluster to
be passed using the transport protocol port. However, it only uses this
to then find the http address.

This change makes ESRestTestCase extend from ESTestCase instead of
ESIntegTestCase, and changes the sysprop used to tests.rest.cluster,
which now takes the http address.

Simon Willnauer aa38d053d7 Simplify Analysis registration and configuration
This change moves all the analysis component registration to the node level
and removes the significant API overhead to register tokenfilter, tokenizer,
charfilter and analyzer. All registration is done without guice interaction such
that real factories via functional interfaces are passed instead of class objects
that are instantiated at runtime.

This change also hides the internal analyzer caching that was done previously in the
IndicesAnalysisService entirely and decouples all analysis registration and creation
from dependency injection.

The @IndexSettings annoationat has been used to differentiate between node-level

the settings object that a class got injected when it was created was static and

and replaces it with a full-fledged class that adds type-safety and encapsulates additional
functionality as well as checks on the settings.

Nik Everett 2cc97a0d3e Remove and ban @Test
There are three ways `@Test` was used. Way one:

```java
@Test
public void flubTheBlort() {
```

This way was always replaced with:

```java
public void testFlubTheBlort() {
```

Or, maybe with a better method name if I was feeling generous.

Way two:

```java
@Test(throws=IllegalArgumentException.class)
public void testFoo() {
    methodThatThrows();
}
```

This way of using `@Test` is actually pretty OK, but to get the tools to ban
`@Test` entirely it can't be used. Instead:

```java
public void testFoo() {
    try {
        methodThatThrows();
        fail("Expected IllegalArgumentException");
    } catch (IllegalArgumentException e ) {
        assertThat(e.getMessage(), containsString("something"));
    }
}
```

This is longer but tests more than the old ways and is much more precise.
Compare:

```java
@Test(throws=IllegalArgumentException.class)
public void testFoo() {
    some();
    copy();
    and();
    pasted();
    methodThatThrows();
    code();  // <---- This was left here by mistake and is never called
}
```

to:

```java
@Test(throws=IllegalArgumentException.class)
public void testFoo() {
    some();
    copy();
    and();
    pasted();
    try {
        methodThatThrows();
        fail("Expected IllegalArgumentException");
    } catch (IllegalArgumentException e ) {
        assertThat(e.getMessage(), containsString("something"));
    }
}
```

The final use of test is:

```java
@Test(timeout=1000)
public void testFoo() {
    methodThatWasSlow();
}
```

This is the most insidious use of `@Test` because its tempting but tragically
flawed. Its flaws are:
1. Hard and fast timeouts can look like they are asserting that something is
faster and even do an ok job of it when you compare the timings on the same
machine but as soon as you take them to another machine they start to be
invalid. On a slow VM both the new and old methods fail. On a super-fast
machine the slower and faster ways succeed.
2. Tests often contain slow `assert` calls so the performance of tests isn't
sure to predict the performance of non-test code.
3. These timeouts are rude to debuggers because the test just drops out from
under it after the timeout.

Confusingly, timeouts are useful in tests because it'd be rude for a broken
test to cause CI to abort the whole build after it hits a global timeout. But
those timeouts should be very very long "backstop" timeouts and aren't useful
assertions about speed.

For all its flaws `@Test(timeout=1000)` doesn't have a good replacement __in__
__tests__. Nightly benchmarks like http://benchmarks.elasticsearch.org/ are
useful here because they run on the same machine but they aren't quick to check
and it takes lots of time to figure out the regressions. Sometimes its useful
to compare dueling implementations but that requires keeping both
implementations around. All and all we don't have a satisfactory answer to the
question "what do you replace `@Test(timeout=1000)`" with. So we handle each
occurrence on a case by case basis.

For files with `@Test` this also:
1. Removes excess blank lines. They don't help anything.
2. Removes underscores from method names. Those would fail any code style
checks we ever care to run and don't add to readability. Since I did this manually
I didn't do it consistently.
3. Make sure all test method names start with `test`. Some used to end in `Test` or start
with `verify` or `check` and they were picked up using the annotation. Without the
annotation they always need to start with `test`.
4. Organizes imports using the rules we generate for Eclipse. For the most part
this just removes `*` imports which is a win all on its own. It was "required"
to quickly remove `@Test`.
5. Removes unneeded casts. This is just a setting I have enabled in Eclipse and
forgot to turn off before I did this work. It probably isn't hurting anything.
6. Removes trailing whitespace. Again, another Eclipse setting I forgot to turn
off that doesn't hurt anything. Hopefully.
7. Swaps some tests override superclass tests to make them empty with
`assumeTrue` so that the reasoning for the skips is logged in the test run and
it doesn't "look like" that thing is being tested when it isn't.
8. Adds an oxford comma to an error message.

The total test count doesn't change. I know. I counted.
```bash
git checkout master && mvn clean && mvn install | tee with_test
git no_test_annotation master && mvn clean && mvn install | tee not_test
grep 'Tests summary' with_test > with_test_summary
grep 'Tests summary' not_test > not_test_summary
diff with_test_summary not_test_summary
```

These differ somewhat because some tests are skipped based on the random seed.
The total shouldn't differ. But it does!
```
1c1
< [INFO] Tests summary: 564 suites (1 ignored), 3171 tests, 31 ignored (31 assumptions)
---
> [INFO] Tests summary: 564 suites (1 ignored), 3167 tests, 17 ignored (17 assumptions)
```

These are the core unit tests. So we dig further:
```bash
cat with_test | perl -pe 's/\n// if /^Suite/;s/.*\n// if /IGNOR/;s/.*\n// if /Assumption #/;s/.*\n// if /HEARTBEAT/;s/Completed .+?,//' | grep Suite > with_test_suites
cat not_test | perl -pe 's/\n// if /^Suite/;s/.*\n// if /IGNOR/;s/.*\n// if /Assumption #/;s/.*\n// if /HEARTBEAT/;s/Completed .+?,//' | grep Suite > not_test_suites
diff <(sort with_test_suites) <(sort not_test_suites)
```

The four tests with lower test numbers are all extend `AbstractQueryTestCase`
and all have a method that looks like this:

```java
@Override
public void testToQuery() throws IOException {
    assumeTrue("test runs only when at least a type is registered", getCurrentTypes().length > 0);
    super.testToQuery();
}
```

It looks like this method was being double counted on master and isn't anymore.

Ryan Ernst 45f757de6d Test: Move rest-api-spec for plugins into test resources
Plugin tests require having rest-api tests, and currently copy that spec

David Pilato a38bcc5d62 [test] plugins simple RestIT tests don't work from IDE
When running a RestIT test from the IDE, you actually start an internal node which does not automatically load the plugin you would like to test.

We need to add:

```java
    @Override
    protected Collection<Class<? extends Plugin>> nodePlugins() {
        return pluginList(PLUGIN_HERE.class);
    }
```

Everything works fine when running from maven because each test basically:

* installs elasticsearch
* installs one plugin
* starts elasticsearch with this plugin loaded
* runs the test

Note that this PR only fixes the fact we run an internal cluster with the expected plugin.

Cloud tests will still fail when run from the IDE because is such a case you actually start an internal node with many mock plugins.
And REST test suite for cloud plugins basically checks if the plugin is running by checking the output of NodesInfo API.

And we check:

```yml
- match:  { nodes.$master.plugins.0.name: cloud-azure  }
- match:  { nodes.$master.plugins.0.jvm: true  }
```

But in that case, this condition is certainly false as we started also `mock-transport-service`, `mock-index-store`, `mock-engine-factory`, `node-mocks`, `asserting-local-transport`, `mock-search-service`.

Closes #13479

Ryan Ernst 2bf84593e0 Plugins: Simplify Plugin API for constructing modules
The Plugin interface currently contains 6 different methods for
adding modules. Elasticsearch has 3 different levels of injectors,
and for each of those, there are two methods. The first takes no
arguments and returns a collection of class objects to construct. The
second takes a Settings object and returns a collection of module
objects already constructed. The settings argument is unecessary because
the plugin can already get the settings from its constructor. Removing
that, the only difference between the two versions is returning an
already constructed Module, or a module Class, and there is no reason
the plugin can't construct all their modules themselves.

This change reduces the plugin api down to just 3 methods for adding
modules. Each returns a Collection<Module>. It also removes the
processModule method, which was unnecessary since onModule
implementations fullfill the same requirement. And finally, it renames
the modules() method to nodeModules() so it is clear these are created
once for each node.

Ryan Ernst 2450e3ccc8 Internal: Flatten IndicesModule and add tests
The IndicesModule was made up of two submodules, one which
handled registering queries, and the other for registering
hunspell dictionaries. This change moves those into
IndicesModule. It also adds a new extension point type,
InstanceMap. This is simply a Map<K,V>, where K and V are
actual objects, not classes like most other extension points.
I also added a test method to help testing instance map extensions.
This was particularly painful because of how guice binds the key
and value as separate bindings, and then reconstitutes them
into a Map at injection time. In order to gain access to the
object which links the key and value, I had to tweak our
guice copy to not use an anonymous inner class for the Provider.

Note that I also renamed the existing extension point types, since
they were very redundant. For example, ExtensionPoint.MapExtensionPoint
is now ExtensionPoint.ClassMap.

See #12783.
