* Removed `Template` class and unified script & template parsing logic. Templates are scripts, so they should be defined as a script. Unless there will be separate template infrastructure, templates should share as much code as possible with scripts.
* Removed ScriptParseException in favour for ElasticsearchParseException
* Moved TemplateQueryBuilder to lang-mustache module because this query is hard coded to work with mustache only
This change removes the multiple ways that plugins can be added to the
integ test cluster. It also removes the use of the default
configuration, and instead adds a zip configuration to all plugins. This
will enable using project substitutions with plugins, which must be done
with the default configuration.

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).

This should make them easier to read and adds them to the test suite
I changed the example from a two node cluster to a single node cluster
because that is what we have running in the integration tests. It is also
what a user just starting out is likely to see so I think that is ok.

This commit adds a log message when bootstrap checks are enforced
informing the user that they are enforced because they are bound to an
external network interface. We also log if bootstrap checks are being
enforced but system checks are being ignored.

The unit tests for IndicesClusterStateService currently inject random failures upon shard creation/ routing upate / mapping update etc. This commit makes injecting failures optional so that stronger assertions can be made about the local indices / shard state in case of no failures.
Before returning, index creation now waits for the configured number
of shard copies to be started. In the past, a client would create an
index and then potentially have to check the cluster health to wait
to execute write operations. With the cluster health semantics changing
so that index creation does not cause the cluster health to go RED,
this change enables waiting for the desired number of active shards
to be active before returning from index creation.

For historical reasons, the value associated with Priority.IMMEDIATE is
-1. Yet, with a full-cluster restart required on major version upgrades,
we can reset these values so they are conceptually simpler. This commit
resets the values associated with Priority instances.
Today we have an abstraction Priority for representing
priorities. Ideally, these values are a fixed set of constants with a
well-defined ordering which sounds perfect for an enum. This commit
changes Priority so that it is an enum instead of a class.
In Priority there is a field named values that represents an ordered, by
priority, list of all priorities. Yet, this collection is modifiable and
this collection is exposed via the public API. This means that consumers
can modify this list potentially leading to complete chaos. This commit
modifies this field so that it is unmodifiable, documents that the
returned collection is unmodifiable, and returns total order to the
world. We also punish the bad consumer here by making them make a copy
of the returned collection with which they can do as they please. This
fixes a puzzling test failure which only arises if the two tests
(PrioritizedExecutorsTests#testPriorityQueue and
PriorityTests#testCompareTo run in the same JVM, and run in the right
order).

Moving the dependent jars instead of copying breaks downstream builds
that rely on the jars existing for compilation. This commit modifies
these moves to be copies.
Also introduced a `Processor.Parameters` class that is holder for several services processors rely on,
the IngestPlugin#getProcessors(...) method has been changed to accept `Processor.Parameters` instead
of each service seperately.
Today we log all loaded modules and installed plugins in a single
line. The number of modules has grown, and when plugins are installed a
single log line containing the loaded modules and plugins is
lengthy. With this commit, we log a single module or plugin per line,
log these in sorted order, and also log if no modules or no plugins were
loaded.

This commit renames the Netty 3 transport module from transport-netty to
transport-netty3. This is to make room for a Netty 4 transport module,
transport-netty4.
Relates #19439
Currently custom headers that should be passed through rest requests are
registered by depending on the RestController in guice and calling a
registration method. This change moves that registration to a getter for
plugins, and makes the RestController take the set of headers on
construction.
Invocation counts can be used to help judge the selectivity of individual query components in the context of the entire query. E.g. a query may not look selective when run by itself (matches most of the index), but when run in context of a full search request, is evaluated only rarely due to execution order
Since this is modifying the base timing class, it'll enrich both query and agg profiles (as well as future profile results)
Today `node.mode` and `node.local` serve almost the same purpose, they
are a shortcut for `discovery.type` and `transport.type`. If `node.local: true`
or `node.mode: local` is set elasticsearch will start in _local_ mode which means
only nodes within the same JVM are discovered and a non-network based transport
is used. The _local_ mode it only really used in tests or if nodes are embedded.
For both, embedding and tests explicit configuration via `discovery.type` and `transport.type`
should be preferred.
This change removes all the usage of these settings and by-default doesn't
configure a default transport implemenation since netty is now a module. Yet, to make
the user expericence flawless, plugins or modules can set a `http.type.default` and
`transport.type.default`. Plugins set this via `PluginService#additionalSettings()`
which enforces _set-once_ which prevents node startup if set multiple times. This means
that our distributions will just startup with netty transport since it's packaged as a
module unless `transport.type` or `http.transport.type` is explicitly set.
This change also found a bunch of bugs since several NamedWriteables were not registered if a
transport client is used. Now that we don't rely on the `node.mode` leniency which is inherited
instead of using explicit settings, `TransportClient` uses `AssertingLocalTransport` which detects these problems since it serializes all messages.
Closes#16234
The Java API supports this while mostly used for tests it can also be useful in
production environments. For instance if something is automated like a settings change
and we execute some health right after it the settings update might have some consequences
like a reroute which hasn't been fully applied since the preconditions are not fulfilled yet.
For instance if not all shards started the settings update is applied but the reroute won't move
currently initializing shards like in the shrink API test. Sure this could be done by waiting for
green before but if the cluster moves shards due to some side-effects waiting for all events is
still useful. I also took the chance to add unittests to Priority.java
Closes#19419
This changes adds a flag which can be set in the esplugin closure in
build.gradle for plugins and modules which contain pieces that must be
published to maven, for use in the transport client. The jar/pom and
source/javadoc jars are moved to a new name that has the suffix
"-client".
I enabled this for the two modules that I know definitely need this;
there may be more. One open question is which groupId to use for the
generated pom.

This adds an extra method, registerWithDeprecatedHandler, to register both a normal handler and a deprecated handler at the same time. This helps with renaming methods as opposed to _just_ deprecated methods.
