This commit adds a -q/--quiet option to Elasticsearch so that it does not log anything in the console and closes stdout & stderr streams. This is useful for SystemD to avoid duplicate logs in both journalctl and /var/log/elasticsearch/elasticsearch.log while still allows the JVM to print error messages in stdout/stderr if needed.

This commit adds a health status parameter to the cat indices API for
filtering on indices that match the specified status (green|yellow|red).

Previously when trying to listen on virtual interfaces during
bootstrap the application would stop working - the interface
couldn't be found by the NetworkUtils class.
The NetworkUtils utilize the underlying JDK NetworkInterface
class which, when asked to lookup by name only takes physical
interfaces into account, failing at virtual (or subinterfaces)
ones (returning null).
Note that when interating over all interfaces, both physical and
virtual ones are taken into account.
This changeset asks for all known interfaces, iterates over them
and matches on the given name as part of the loop, allowing it
to catch both physical and virtual interfaces.
As a result, elasticsearch can now also serve on virtual
interfaces.
A test case has been added which makes sure that all
iterable interfaces can be found by their respective name.
Note that this PR is a second iteration over the previously
merged but later reverted #19537 because it causes tests
to fail when interfaces are down. The test has been modified
to take this into account now.

Add docs to template support for _msearch

* Reference those docs from the rest api spec for _msearch/template support.
Match query throws parsing errors when an array of terms is provided, we should test that to make sure this behaviour doesn't change.

Once a primary is marked as relocated, we can not safely move it back to started (as we have no way of waiting on inflight operations that are performed on the target primary). If the master cancels the relocation in that state, we fail the primary. Sadly, there is a racing condition between the `updateRoutingEntry` method (which is called when the relocation is cancelled by the master) and the `relocated` method. That racing condition can leave the shard as marked "relocated" but have the routing entry not reflect the target relocation. This in turns causes NPEs in TransportReplicationAction:
```
java.util.Objects requireNonNull Objects.java 203
org.elasticsearch.action.support.replication.TransportReplicationAction$ConcreteShardRequest <init> TransportReplicationAction.java 982
```
Sadly, once we end up in this state, we will never recover.
This commit fixes that race condition by making sure `updateRoutingEntry` acquires the mutex when checking for the relocated status. While at it, I also tightened up the code and added lots of assertions/hard checks.
Adds the entire DiscoveryNode object to the trace log in AllocationDeciders.
The allocation decider logging at TRACE level can sometimes be helpful to determine why a shard is not getting allocated on specific nodes. Currently, we only log the node id for these messages. It will be helpful to also include the node name (esp. when dealing with a lot of nodes in the cluster).
memory are much less than the total memory, the percentage
returned could be 0%. The yaml tests check that the free/used
percentage are valid values by asserting `is_true`, but it
turns out that `is_true` returns false if the value is
assigned but it is 0 or even the string "0". This commit
changes the assertion in the yaml test to ensure the value
is greater than or equal to 0 instead.
The plugin command now displays the version of the plugin, which is
compared to a string without the version. This removes the version from
the string.
In 5.x we allowed this with a deprecation warning. This removes the code
added for that deprecation, requiring the cluster name to not be in the
data path.
Resolves#20391
This change removes the guice dependency handling for SearchService and
several related classes like SearchTransportController and SearchPhaseController.
The latter two now have package private constructors and dependencies like FetchPhase
are now created by calling their constructors explicitly. This also cleans up several users
of the DefaultSearchContext and centralized it's creation inside SearchService.
The cause early termination of tests, which means we don't clean up and close shards, but also don't cause a failure. This in turns makes TestRuleTemporaryFilesCleanup fail on windows (because it does try to clean up, but the files are referenced). Getting stuff like:
```

```
Splits the PrimaryShardAllocator and ReplicaShardAllocator's decision
making for a shard from the implementation of that decision on the
routing table. This is a step toward making it easier to use the same
logic for the cluster allocation explain APIs.
Introduce a base class for unit tests that are based on real `IndexShard`s. The base class takes care of all the little details needed to create and recover shards.
This commit also moves `IndexShardTests` and `ESIndexLevelReplicationTestCase` to use the new base class. All tests in `IndexShardTests` that required a full node environment were moved to a new `IndexShardIT` suite.
Before, when there was a new cluster state to publish,
zen discovery would first update the set of nodes to
ping based on the new cluster state, then publish the new
cluster state. This is problematic because if the cluster
state failed to publish, then the set of nodes to ping
should not have been updated.
This commit fixes the issue by updating the set of
nodes to ping for fault detection only *after* the new
cluster state has been published.
We should rather throw a clear exception to clearly point out that we cannot extract fields from _source. Note that this happens only when explicitly trying to extract fields from source. When source is disabled and no _source parameter is specified, no errors will be thrown and no source will be returned.

The JDK project is in the process of modifying the command-line flags
for various JDK tools (http://openjdk.java.net/jeps/293). In particular,
the release flag on javac has changed from -release to --release. This
commit adapts the build process to this change.

The evil logger tests rely on external configuration. This configuration
is shared between these tests which means that changing the
configuration for one test can cause an unrelated test to fail. In
particular, removing the appenders on the root logger so that inherited
loggers in one test do not have a console and file appender by default
breaks tests that were expecting the root logger to have these
appenders. This commit separates these configs so that these tests are
not subject to this problem.
The Elasticsearch startup scripts contain checks for the presence of
support for environment variables that were removed in the 5.x
series. These checks warn the user and fail the script if any of the
unsupported environment variables are present. This was provided as
migration step from 2.x to 5.x so that we were not just silently
ignoring environment variables that were previously set. This commit
removes these checks, as upgrades from 2.x to 6.x are not supported.

Search section supports an ext section that is used to provide additional config needed from plugins. It is now tied to sub fetch phases because it is the only section that may need additional config, but there is no reason for the two to be tightly coupled.
It is now possible to register a searchExtParser independently from a sub fetch phase. All a search ext parser does is parsing some ext section of a search request, whose parsed resulting object is stored in the search context for later retrieval.
The parser is now needed only for sub fetch phases, but doesn't have to be strictly connected to them, it could be used for something else as well potentially
The context was an object where the parsed info are stored. That is more of what we call the builder since after the search refactoring. No need for generics in FetchSubPhaseParser then. Also the previous setHitsExecutionNeeded wasn't useful, it can be removed as well, given that once there is a parsed ext section, it will become a builder that can be retrieved by the sub fetch phase. The sub fetch phase is responsible for doing nothing in case the builder is not set, meaning that the fetch sub phase is plugged in but the request didn't have the corresponding section.
SearchParseElement is renamed to FetchSubPhaseParser and moved to the search.fetch package. Its parse method doesn't get the SearchContext as argument anymore, only the XContentParser, and the return type is what gets parsed (the fetch sub phase context which we may as well rename later).
It is the parser that initializes the FetchSubPhaseContext then. SearchService retrieves the parser by name, calls parse against it and stores the result of parsing by name. No need for FetchSubPhase.ContextFactory anymore, which can be removed.
Given that doc value fields is our own fetch sub phase, it doesn't need to be implemented like if it was plugged in from the outside. It doesn't need its own fetch sub phase context, but it can just be an instance member in SearchContext
