IndexShard currently holds an arbitraritly used `getQueryShardContext` that comes
out of a ThreadLocal. It's usage is undefined and arbitraty since there is also
such a method with different semantics on `IndexService` This commit removes the threadLocal on
IndexShard as well as on the context itself. It's types are now a member and the QueryShardContext
lifecycle is managed byt SearchContext which passes the types on from the SearchRequest.
Recovery from store fails to correctly set the translog recovery stats. This fixes it and tightens up the logic bringing it all to IndexShard (previously it was set by the recovery logic).

This commit modifies the MessageDigests message digest provider to
return a thread local instance of MessageDigest instances instead of
using clone since some providers do not support clone.

* Minor clean up of Writer constants.
* Removed synthetic attribute from the generated constructor and method.
* Added a safeguard for maximum script length.

There is no need for IndicesWarmer to be a global accessible class. All it needs
access to is inside IndexService. It also doesn't need to be mutable once it's not a per node
instance. This commit move IndicesWarmer to IndexWarmer and makes the default impls like field data and
norms warming an impl detail. Also the IndexShard doesn't depend on this class anymore, instead it accepts
an Engine.Warmer as a ctor argument which delegates to the actual warmer from the index.
The cat API previously used the Content-Type header field for
determining the media type of the response. This is in opposition to the
HTTP spec which specifies the Accept header field for this purpose. This
commit replaces the use of the Content-Type header field with the Accept
header field in the cat API.
Closes#14421
One of our tests leaked a system property here since we failed after appling some
system properties in BootstrapCLIParser. This is not a huge deal in production since
we exit the JVM if we fail on that. Yet for correctnes we should only apply them if
we manage to parse them all.
This also caused a test failure lately on CI but on an unrelated test:

Indices level field data cacheing belongs into IndicesService and doesn't need to be
wired by guice. This commit also moves the async cache refresh out of the class into
IndicesService such that threadpool dependencies are removed and testing / creation becomes
simpler.
This processor is useful when all elements of a json array need to be processed in the same way.
This avoids that a processor needs to be defined for each element in an array.
Also it is very likely that it is unknown how many elements are inside an json array.
Modules are an internal implementation detail of our build, and there is
no need to publish them with gradle. This change disables publishing of
all modules.
140 characters is our official line length from CONTRIBUTING.md. It is a
little longer than fits well in github but you can use a userstyle to fix
that. It is perfect for Eclipse and unified diffs but too wide for side by
side diffs. Regardless, its the official limit we've had for years. We just
haven't enforced it automatically and we haven't enforced it using github
because line limits are hard to notice there.
This only hits about 2/3 of the java files - those that didn't have failures
already. If they did have a failure it suppresses them. We should pick files
off that list as time goes on.
For posterity I generated the suppressions by running checkstyle with
ignoreFailures = true, piping the output to a file, and then running it
through this:
perl -ne 'print if s{.*\[ant:checkstyle\] /.+/elasticsearch/}{ <suppress files="} && s{\.java.+}{\.java" checks="LineLength" />}' | uniq
Retrieving distributed DF for TermVectors is beside it's esotheric justification
a very slow process and can cause serious load on the cluster. We also don't have nearly
enough testing for this stuff and given the complexity we should remove it rather than carrying it
around.
