ReduceContext contains the list of aggregations to reduce but these aggregations are set as null half of the time. This change makes the reduce(ReduceContext) method changed to reduce(List<InternalAggregation>, ReduceContext) and ReduceContext now only holds the BigArrays and Script services.
* In code, we mark `River`, `AbstractRiverComponent`, `RiverComponent` and `RiverName` classes as deprecated
* We log that information when a cluster is still using it
* We add this information in the plugins list as well
Today we check every regular expression eagerly against every possible term.
This can be very slow if you have lots of unique terms, and even the bottleneck
if your query is selective.
This commit switches to Lucene regular expressions instead of Java (not exactly
the same syntax yet most existing regular expressions should keep working) and
uses the same logic as RegExpQuery to intersect the regular expression with the
terms dictionary. I wrote a quick benchmark (in the PR) to make sure it made
things faster and the same request that took 750ms on master now takes 74ms with
this change.

The refactoring in #9544 introduced a regression that broke multi-level
aggregations using breadth-first. This was due to sub-aggregators creating
deferred collectors before their parent aggregator and then the parent
aggregator trying to collect sub aggregators directly instead of going through
the deferred wrapper.
This commit fixes the issue but we should try to simplify all the pre/post
collection logic that we have.
Also `breadth_first` is now automatically ignored if the sub aggregators need
scores (just like we ignore `execution_mode` when the value does not make sense
like using ordinals on a script).

To ensure subclasses like MockInternalEngine which is in a different
package (test.engine) are logging under the same logger name this commit
moves to a static logger class to determin the logger name. This way
all subclasses of engine will log under `index.engine` which also plays
nicely with `@TestLogging` where log messages sometimes disappeared since
they were enabled for the `index.engine` package but not for `test.engine`
Commit 168238dab6 declared multiple maven-resources-plugin usages instead of declaring multiple executions for the same plugin... resulting to Maven warnings.

If the translog is buffered we must make sure everything is synced to disk
before we rollback the writer otherwise we open a window for potential dataloss due
to stupid errors preventing the translog from being closed.
For bacwards compatibility reasons routing_nodes were previously printed out when routing_table was requested, together with the actual routing_table. Now they are printed out only when requests through `routing_nodes` flag.
Relates to #10412Closes#10486
Cluster state api returns both routing_table and routing_nodes sections whenever routing_table is requested. That is pretty much the same info, just grouped differently. This commit allows to differentiate between the two. Yet, routing_table still returns both for bw comp reasons.

Removed the following methods from `ScriptService`, which don't require the `ScriptContext` argument:
```
public CompiledScript compile(String lang, String script, ScriptType scriptType)
public ExecutableScript executable(String lang, String script, ScriptType scriptType, Map<String, Object> vars)
public SearchScript search(SearchLookup lookup, String lang, String script, ScriptType scriptType, @Nullable Map<String, Object> vars)
```
Also removed the ScriptContext.Standard.GENERIC_PLUGIN enum value, as it was used only for backwards compatibility.
Plugins that make use of scripts should declare their own script contexts through `ScriptModule#registerScriptContext` and use them when compiling/executing scripts.
Closes#10476
Plugins can now define multiple operations/contexts that they use scripts for. Fine-grained settings can then be used to enable/disable scripts based on each single registered context.
Also added a new generic category called `plugin`, which will be used as a default when the context is not specified. This allows us to restore backwards compatibility for plugins on `ScriptService` by restoring the old methods that don't require the script context and making them internally use the `plugin` context, as they can only be called from plugins.
Closes#10347Closes#10419
Align get indexed scripts and get search template apis to our get api, which returns a response body when the document is not found, with a found boolean flag. Also, return metadata info all the time too.
Closes#7325Closes#10396
This tests adds a mappings with {"fielddata": {"format": "doc_values"}} but the
default mapping has {"doc_values": false} so when the document mapper parsing
logic merges both we have {"doc_values": false,"fielddata": {"format": "doc_values"}}
and {"doc_values": false} wins, so the test is not using doc values while it
thought it would.
In several places in the code we need to notify a node it needs to do something (typically the master). When that node is the local node, we have an optimization in serveral places that runs the execution code immediately instead of sending the request through the wire to itself. This is a shame as we need to implement the same pattern again and again. On top of that we may forget (see note bellow) to do so and we might have to write some craft if the code need to run under another thread pool.
This commit folds the optimization in the TrasnportService, shortcutting wire serliazition if the target node is local.
Note: this was discovered by #10247 which tries to import a dangling index quickly after the cluster forms. When sending an import dangling request to master, the code didn't take into account that fact that the local node may master. If this happens quickly enough, one would get a NodeNotConnected exception causing the dangling indices not to be imported. This will succeed after 10s where InternalClusterService.ReconnectToNodes runs and actively connects the local node to itself (which is not needed), potentially after another cluster state update.
Closes#10350
The exceptionCaught method had default access, which imposes a requirement
for subclasses that need to override this method to be in a specific package. This
change simply makes the method protected, which removes the package requirement.
We still have a lot of APIs that use setNextReader in order to change the
current segment that should be considered. This commit moves such APIs to
getLeafXXX() instead to be more in-line with Lucene 5's collector API.
I also renamed setDocId to setDocument to be more in-line with the doc values
APIs.
