Always use deprecateAndMaybeLog for deprecation warnings (#55319)
Backport of #55115.

Replace calls to deprecate(String,Object...) with deprecateAndMaybeLog(...),
with an appropriate key, so that all messages can potentially be deduplicated.

David Turner 7941f4a47e Add RepositoriesService to createComponents() args (#54814)
Today we pass the `RepositoriesService` to the searchable snapshots plugin
during the initialization of the `RepositoryModule`, forcing the plugin to be a
`RepositoryPlugin` even though it does not implement any repositories.

After discussion we decided it best for now to pass this in via
`Plugin#createComponents` instead, pending some future work in which plugins
can depend on services more dynamically.

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.

Alan Woodward d23112f441 Report parser name and location in XContent deprecation warnings (#53805)
It's simple to deprecate a field used in an ObjectParser just by adding deprecation
markers to the relevant ParseField objects. The warnings themselves don't currently
have any context - they simply say that a deprecated field has been used, but not
where in the input xcontent it appears. This commit adds the parent object parser
name and XContentLocation to these deprecation messages.

Note that the context is automatically stripped from warning messages when they
are asserted on by integration tests and REST tests, because randomization of
xcontent type during these tests means that the XContentLocation is not constant

Single instance of the IndexNameExpressionResolver (#52604)
This commit modifies the codebase so that our production code uses a
single instance of the IndexNameExpressionResolver class. This change
is being made in preparation for allowing name expression resolution
to be augmented by a plugin.

In order to remove some instances of IndexNameExpressionResolver, the
single instance is added as a parameter of Plugin#createComponents and
PersistentTaskPlugin#getPersistentTasksExecutor.

Jay Modi 3edadfefd0 RestHandlers declare handled routes (#52123)
This commit changes how RestHandlers are registered with the
RestController so that a RestHandler no longer needs to register itself
with the RestController. Instead the RestHandler interface has new
methods which when called provide information about the routes
(method and path combinations) that are handled by the handler
including any deprecated and/or replaced combinations.

This change also makes the publication of RestHandlers safe since they
no longer publish a reference to themselves within their constructors.

Closes #51622

Copy http headers to ThreadContext strictly (#45945) (#48675)
Previous behavior while copying HTTP headers to the ThreadContext,
would allow multiple HTTP headers with the same name, handling only
the first occurrence and disregarding the rest of the values. This
can be confusing when dealing with multiple Headers as it is not
obvious which value is read and which ones are silently dropped.

According to RFC-7230, a client must not send multiple header fields
with the same field name in a HTTP message, unless the entire field
value for this header is defined as a comma separated list or this
specific header is a well-known exception.

This commits changes the behavior in order to be more compliant to
the aforementioned RFC by requiring the classes that implement
ActionPlugin to declare if a header can be multi-valued or not when
registering this header to be copied over to the ThreadContext in
ActionPlugin#getRestHeaders.
If the header is allowed to be multivalued, then all such headers
are read from the HTTP request and their values get concatenated in
a comma-separated string.
If the header is not allowed to be multivalued, and the HTTP
request contains multiple such Headers with different values, the
request is rejected with a 400 status.

Remove use of Setting#getRaw in deprecation tests (#47262)
This commit removes a use of Setting#getRaw from the deprecation header
tests. The use of Setting#getRaw is not needed here, the x-content
infrastructure will take care of emitting the appropriate values here,
and so the caller does not need to convert these to string
representations of the settings values.

Convert most awaitBusy calls to assertBusy (#45794) (#47112)
Backport of #45794 to 7.x. Convert most `awaitBusy` calls to
`assertBusy`, and use asserts where possible. Follows on from #28548 by
@liketic.

There were a small number of places where it didn't make sense to me to
call `assertBusy`, so I kept the existing calls but renamed the method to
`waitUntil`. This was partly to better reflect its usage, and partly so
that anyone trying to add a new call to awaitBusy wouldn't be able to find
it.

I also didn't change the usage in `TransportStopRollupAction` as the
comments state that the local awaitBusy method is a temporary
copy-and-paste.

Other changes:

  * Rework `waitForDocs` to scale its timeout. Instead of calling
    `assertBusy` in a loop, work out a reasonable overall timeout and await
    just once.
  * Some tests failed after switching to `assertBusy` and had to be fixed.
  * Correct the expect templates in AbstractUpgradeTestCase.  The ES
    Security team confirmed that they don't use templates any more, so
    remove this from the expected templates. Also rewrite how the setup
    code checks for templates, in order to give more information.
  * Remove an expected ML template from XPackRestTestConstants The ML team
    advised that the ML tests shouldn't be waiting for any
    `.ml-notifications*` templates, since such checks should happen in the
    production code instead.
  * Also rework the template checking code in `XPackRestTestHelper` to give
    more helpful failure messages.
  * Fix issue in `DataFrameSurvivesUpgradeIT` when upgrading from < 7.4

Core: Less settings to AbstractComponent (#35140)
Stop passing `Settings` to `AbstractComponent`'s ctor. This allows us to
stop passing around `Settings` in a *ton* of places. While this change
touches many files, it touches them all in fairly small, mechanical
ways, doing a few things per file:
1. Drop the `super(settings);` line on everything that extends
`AbstractComponent`.
2. Drop the `settings` argument to the ctor if it is no longer used.
3. If the file doesn't use `logger` then drop `extends
AbstractComponent` from it.
4. Clean up all compilation failure caused by the `settings` removal
and drop any now unused `settings` isntances and method arguments.

I've intentionally *not* removed the `settings` argument from a few
files:
1. TransportAction
2. AbstractLifecycleComponent
3. BaseRestHandler

These files don't *need* `settings` either, but this change is large
enough as is.

Core: Drop settings member from AbstractComponent (#35083)
Drops the `Settings` member from `AbstractComponent`, moving it from the
base class on to the classes that use it. For the most part this is a
mechanical change that doesn't drop `Settings` accesses. The one
exception to this is naming threads where it switches from an invocation
that passes `Settings` and extracts the node name to one that explicitly
passes the node name.

This change doesn't drop the `Settings` argument from
`AbstractComponent`'s ctor because this change is big enough as is.
We'll do that in a follow up change.

HLRest: Allow caller to set per request options (#30490)
This modifies the high level rest client to allow calling code to
customize per request options for the bulk API. You do the actual
customization by passing a `RequestOptions` object to the API call
which is set on the `Request` that is generated by the high level
client. It also makes the `RequestOptions` a thing in the low level
rest client. For now that just means you use it to customize the
headers and the `httpAsyncResponseConsumerFactory` and we'll add
node selectors and per request timeouts in a follow up.

I only implemented this on the bulk API because it is the first one
in the list alphabetically and I wanted to keep the change small
enough to review. I'll convert the remaining APIs in a followup.

Network: Remove http.enabled setting (#29601)
This commit removes the http.enabled setting. While all real nodes (started with bin/elasticsearch) will always have an http binding, there are many tests that rely on the quickness of not actually needing to bind to 2 ports. For this case, the MockHttpTransport.TestPlugin provides a dummy http transport implementation which is used by default in ESIntegTestCase.

Decouple XContentBuilder from BytesReference (#28972)
* Decouple XContentBuilder from BytesReference

This commit removes all mentions of `BytesReference` from `XContentBuilder`.
This is needed so that we can completely decouple the XContent code and move it
into its own dependency.

While this change appears large, it is due to two main changes, moving
`.bytes()` and `.string()` out of XContentBuilder itself into static methods
`BytesReference.bytes` and `Strings.toString` respectively. The rest of the
change is code reacting to these changes (the majority of it in tests).

Jay Modi 7520a107be Optionally require a valid content type for all rest requests with content (#22691)
This change adds a strict mode for xcontent parsing on the rest layer. The strict mode will be off by default for 5.x and in a separate commit will be enabled by default for 6.0. The strict mode, which can be enabled by setting `http.content_type.required: true` in 5.x, will require that all incoming rest requests have a valid and supported content type header before the request is dispatched. In the non-strict mode, the Content-Type header will be inspected and if it is not present or not valid, we will continue with auto detection of content like we have done previously.

The content type header is parsed to the matching XContentType value with the only exception being for plain text requests. This value is then passed on with the content bytes so that we can reduce the number of places where we need to auto-detect the content type.

As part of this, many transport requests and builders were updated to provide methods that
accepted the XContentType along with the bytes and the methods that would rely on auto-detection have been deprecated.

In the non-strict mode, deprecation warnings are issued whenever a request with body doesn't provide the Content-Type header.

Nik Everett 6265ef1c1b Deguice rest handlers (#22575)
There are presently 7 ctor args used in any rest handlers:
* `Settings`: Every handler uses it to initialize a logger and
  some other strange things.
* `RestController`: Every handler registers itself with it.
* `ClusterSettings`: Used by `RestClusterGetSettingsAction` to
  render the default values for cluster settings.
* `IndexScopedSettings`: Used by `RestGetSettingsAction` to get
  the default values for index settings.
* `SettingsFilter`: Used by a few handlers to filter returned
  settings so we don't expose stuff like passwords.
* `IndexNameExpressionResolver`: Used by `_cat/indices` to
  filter the list of indices.
* `Supplier<DiscoveryNodes>`: Used to fill enrich the response
  by handlers that list tasks.

We probably want to reduce these arguments over time but
switching construction away from guice gives us tighter
control over the list of available arguments.

These parameters are passed to plugins using
`ActionPlugin#initRestHandlers` which is expected to build and
return that handlers immediately. This felt simpler than
returning an reference to the ctors given all the different
possible args.

Breaks java plugins by moving rest handlers off of guice.

The way we supported it once we moved query parsing to the coordinating node was having an Optional<QueryBuilder> return type in all of our parse methods (called fromXContent). See #17624. The central place for this was QueryParseContext#parseInnerQueryBuilder. We can now remove all the optional return types and simply throw an exception whenever an empty query is found.

Ryan Ernst c8f241f284 Plugins: Remove response action filters (#21950)
Action filters currently have the ability to filter both the request and
response. But the response side was not actually used. This change
removes support for filtering responses with action filters.
