This adds HTTP pipelining support to netty. Previously pipelining was not
supported due to the asynchronous nature of elasticsearch. The first request
that was returned by Elasticsearch, was returned as first response,
regardless of the correct order.
The solution to this problem is to add a handler to the netty pipeline
that maintains an ordered list and thus orders the responses before
returning them to the client. This means, we will always have some state
on the server side and also requires some memory in order to keep the
responses there.
Pipelining is enabled by default, but can be configured by setting the
http.pipelining property to true|false. In addition the maximum size of
the event queue can be configured.
The initial netty handler is copied from this repo

This changes the weighing function for the filter cache to use a
configurable minimum weight for each filter cached. This value defaults
to 1kb and can be configured with the
`indices.cache.filter.minimum_entry_weight` setting.
This also fixes an issue with the filter cache where the concurrency
level of the cache was exposed as a setting, but not used in cache
construction.

This adds a Listener interface to the ClusterInfoService, this is used
by the DiskThresholdDecider, which adds a listener to check for nodes
passing the high watermark. If a node is past the high watermark an
empty reroute is issued so shards can be reallocated if desired.
A reroute will only be issued once every
`cluster.routing.allocation.disk.reroute_interval`, which is "60s" by
default.
Refactors InternalClusterInfoService to delegate the nodes stats and
indices stats gathering into separate methods so they have be overriden
by extending classes. Each stat gathering method returns a
CountDownLatch that can be used to wait until processing for that part
is successful before calling the listeners.
Fixes#8146
As that environment variable can contain elasticsearch specific configuration
like the path to a configuration, it makes sense to support in both
elasticsearch commands.

This change corrects the location information gathered by the loggers so that when printing class name, method name, and line numbers in the log pattern, the information from the class calling the logger is used rather than a location within the logger itself.
A reset method has also been added to the LogConfigurator class which allows the logging configuration to be reset. This is needed because if the LoggingConfigurationTests and Log4jESLoggerTests are run in the same JVM the second one to run needs to be able to override the log configuration set by the first

we current check that the recovery is not finished when people access the status local variables. This is wrong and we should check for the refcount being > 0 as it is OK to use the status after it has marked as finished but there are still on going, in-flight reference to it.

The MLT field query is simply replaced by a MLT query set to specififc field.
To simplify code maintenance we should deprecate it in 1.4 and remove it in
2.0.

Today any call to the current randomized context modifies the random
sequence such that cluster initialization is context dependent. If due
to an error for instance a static util method is used like `randomLong`
inside the TestCluster instead of the provided Random instance all
reproducibility guarantees are gone. This commit adds a safe mechanism
to initialize these clusters even if a static helper is used. All none
test scope clusters are now initialized in a private randomized context.
Today we simply close the IW when we have to open a new one if ie.
we change merge settings. Yet, the API is deprecated and under the hood
it commits the IW. For safety we should add the current translog ID and
use rollback instead to not wait for merges.
One can set the headers sent with request by the clients by setting the `request.headers` setting. This commit enables overriding any such set headers directly on the requests.
In case the multicast binding fails (due to socket errors), abort zen
pinging code and throw a better error message
