** The default script language is now maintained in `Script` class.
* Added `script.legacy.default_lang` setting that controls the default language for scripts that are stored inside documents (for example percolator queries). This defaults to groovy.
** Added `QueryParseContext#getDefaultScriptLanguage()` that manages the default scripting language. Returns always `painless`, unless loading query/search request in legacy mode then the returns what is configured in `script.legacy.default_lang` setting.
** In the aggregation parsing code added `ParserContext` that also holds the default scripting language like `QueryParseContext`. Most parser don't have access to `QueryParseContext`. This is for scripts in aggregations.
* The `lang` script field is always serialized (toXContent).

PrecisionAtN and ReciprocalRank are binary evaluation metrics by default that
only distiguish between relevant/irrelevant search results. So far we assumed
that relevant documents are labaled with 1 (irrelevant docs with 0) in the
evaluation request, but this is cumbersome if the ratings are provided on a
larger integer scale and would need to get mapped to a 0/1 value.
This change introduces a threshold parameter on the PrecisionAtN and
ReciprocalRank metric than can be used to set the threshold from which on a
document is considered "relevant". It defaults to 1, so in case of 0/1 ratings
the threshold doesn't have to be set and only ratings with value 0 are
considered to be irrelevant.

When Netty 4 was introduced, it was not the default network
implementation. Some tests were constructed to randomly use Netty 4
instead of the default network implementation. When Netty 4 was made the
default implementation, these tests were not updated. Thus, these tests
are randomly choosing between the default network implementation (Netty
4) and Netty 4. This commit updates these tests to reverse the role of
Netty 3 and Netty 4 so that the randomization is choosing between Netty
3 and the default (again, now Netty 4).

This commit modifies the call sites that allocate a parameterized
message to use a supplier so that allocations are avoided unless the log
level is fine enough to emit the corresponding log message.
This commit upgrades the Netty dependencies from version 4.1.4 to
version 4.1.5. This upgrade brings several bug fixes including the
removal of a obnoxious and scary-looking log message when unsafe is
explicitly disabled.

Instead of get, set and remove we do get, remove and then set to avoid type conflicts in IngestDocument.
If the set still fails we try to restore the original field in ingest document.

Netty3/4 TcpTransport implementations are creating thread factories with a "http_server" thread prefix whereas it should start with "transport_server" and let the "http_server" prefix for the HttpServerTransport implementations.
The network types in use on a cluster can be useful information to have,
so this commit adds aggregate metrics for the network types in use in a
cluster to the cluster stats.

The Netty 4 HTTP server pipeline tests contains two different test
cases. The general idea behind these tests is to submit some requests to
a Netty 4 HTTP server, one test with pipelining enabled and another test
with pipelining disabled. These requests are submitted to two endpoints,
one with a path like /{id} and another with a path like /slow with a
query string parameter sleep. This parameter tells the request handler
how long to sleep for before replying. The idea is that in the case of
the pipelining enabled tests, the requests should come back exactly in
the order submitted, even with some of the requests hitting the slow
endpoint with random sleep durations; this is the guarantee that
pipelining provides. And in the case of the pipelining disabled tests,
requests were randombly submitted to /{id} and /slow with sleep
parameters starting at 600ms and increasing by 100ms for each slow
request constructed. We would expect the requests to come back with the
all the responses to the /{id} requests first because these requests
will execute instantaneously, and then the responses to the /slow
requests. Further, it was expected that the slow requests would come
back ordered by the length of the sleep, the thinking being that 100ms
should be enough of a difference between each request that we would
avoid any race conditions. Sadly, this is not the case, the threads do
sometimes hit race conditions.
This commit modifies the HTTP server pipelining tests to address this
race condition. The modification is that the query string parameter on
the /slow endpoint is removed in favor of just submitting requests to
the path /slow/{id}, where id just used a marker to distinguish each
request. The server chooses a random sleep of at least 500ms for each
request on the slow path. The assertion here then is that the /{id}
responses arrive first, then then /slow responses. We can not make an
assertion on the order of the responses, but we can assert that we did
see every expected response.

This adds roundtrip testing to RankEvalSpec, fixes issues
introduced with the previous roundtrip tests, splits
xcontent generation/parsing from actually checking the resulting
objects to deal with e.g. all evaluation metrics needing
some extra treatment.
Renames QuerySpec to RatedRequest, renames newly introduced xcontent
generation helper to conform with naming conventions.
Fixes several lines that were too long, adds missing types where
needed.
