Doc values significantly reduced heap usage, which results in faster
GCs. This change makes the default for doc values dynamic: any
field that is indexed but not analyzed now has doc values. This only
affects fields on indexes created with 2.0+.

The local DocumentMapper is updated while parsing and dynamic fields are added before
parsing has finished. If parsing fails after a dynamic field has been added already
then the field was not added to the cluster state but was present in the local mapper of this
node. New documents with the same field would not necessarily cause an update either and
after restarting the node the mapping for these fields were lost. Instead the new fields
should always be updated.

We currently have a single bw comp test (FunctionScoreBackwardCompatibilityTests) that requires inline scripts on.
After introducing fine-grained script settings, we moved the internal cluster to use the newer settings, but they are not supported by older nodes started as part of the bw comp tests. Moved script settings out of the default settings, so they won't be part of the ordinary settings when running bw comp tests.
Added logic in FunctionScoreBackwardCompatibilityTests to enable dynamic scripts using the proper setting, depending on the version of the node.
Allow to on/off scripting based on their source (where they get loaded from), the operation that executes them and their language.
The settings cover the following combinations:
- mode: on, off, sandbox
- source: indexed, dynamic, file
- engine: groovy, expressions, mustache, etc
- operation: update, search, aggs, mapping
The following settings are supported for every engine:
script.engine.groovy.indexed.update: sandbox/on/off
script.engine.groovy.indexed.search: sandbox/on/off
script.engine.groovy.indexed.aggs: sandbox/on/off
script.engine.groovy.indexed.mapping: sandbox/on/off
script.engine.groovy.dynamic.update: sandbox/on/off
script.engine.groovy.dynamic.search: sandbox/on/off
script.engine.groovy.dynamic.aggs: sandbox/on/off
script.engine.groovy.dynamic.mapping: sandbox/on/off
script.engine.groovy.file.update: sandbox/on/off
script.engine.groovy.file.search: sandbox/on/off
script.engine.groovy.file.aggs: sandbox/on/off
script.engine.groovy.file.mapping: sandbox/on/off
For ease of use, the following more generic settings are supported too:
script.indexed: sandbox/on/off
script.dynamic: sandbox/on/off
script.file: sandbox/on/off
script.update: sandbox/on/off
script.search: sandbox/on/off
script.aggs: sandbox/on/off
script.mapping: sandbox/on/off
These will be used to calculate the more specific settings, using the stricter setting of each combination. Operation based settings have precedence over conflicting source based ones.
Note that the `mustache` engine is affected by generic settings applied to any language, while native scripts aren't as they are static by definition.
Also, the previous `script.disable_dynamic` setting can now be deprecated.

In #9893, an enabled flag was added for _field_names. However,
backcompat for indexes created before 1.3.0 (when _field_names
was added) was lost. This change corrects the mapper
to always be disabled when used with older indexes that
cannot have _field_names.

Deleting a type from an index is inherently dangerous because
the type can be recreated with new mappings which may conflict
with existing segments still using the old mappings. This
removes the ability to delete a type (similar to how deleting
fields within a type is not allowed, for the same reason).

This adds the Explanation to the explain score again. It is needed
because the explanation of script functions will otherwise not contain
an explanation of _score if boost mode is set to replace.

Fail merge if validate_lat or validate_lon values are not equal. This will prevent inconsistencies between geo_points in a merged index, and parse exceptions for bounding_box and distance filters.
Also merged separate GeoPoint test classes into a single GeoPointFieldMapperTest to be consistent with GeoShapeFieldMapperTests.

* add compiler workarounds for JDK bug JI-9019884
* remove permgen specification during tests (this results in an error on java 9)
* fix threadpool grow/shrink to call methods in the right order (this results in IAE with java 9)
Documentation states false as the default for "validate", "validate_lon", and "validate_lat" leading to confusion as described in issue #9539. This simple fix corrects the documentation and communicates that these fields will be deprecated and removed in upcoming versions.

This reverts commit 166fd04239.
Turns out that having log.warn produces a duplicated warn log, as the same message is already logged warn in NettyTranspo
rt#exceptionCaught.
If a request comes in at the same moment the timeout handler for it runs, we may leak a timeoutInfoHolder and erroneously log "Transport response handler not found of id" . The same issue could cause the request tracer to fire a traceUnresolvedResponse call instead of traceReceivedResponse , causing a failure of testTracerLog ( see #10187 ) .
This commit makes sure timeoutInfoHolder is visible before removing the corresponding RequestHolder. It also unifies the TransportService.Adapter#remove(requestId) with TransportService.Adapter#onResponseReceived(requestId), as they are always called together to indicate a response was received.

When a primary moves to another node, we cancel ongoing recoveries and retry from the primary's new home. At the moment this happens when the primary relocation *starts*. It's a shame as we cancel recoveries that may be close to completion and will finish before the primary has been fully relocated. This commit only triggers the cancelation once the primary relocation is completed.
Next to this, it fixes a race condition between recovery cancellation and the recovery completion. At the moment we may trigger remove a recovered shard just after it was completed. Instead, we should use the recovery cancellation logic to make sure only one code path is followed.
All of the above caused the recoverWhileUnderLoadWithNodeShutdown test to fail (see http://build-us-00.elastic.co/job/es_core_15_debian/32/ ). The test creates an index and then increasingly disallows nodes for it, until only 1 node is left in the allocation filtering rules. Normally, this means we stay in green, but the premature recovery cancellation plus the race condition mentioned above caused a shard to be failed and stay unassigned and the test asserts to fail. This happens due to the following sequence:
- The shard has finished recovering and sent the master a shard started command.
- The recovery is cancelled locally, removing the index shard.
- Master starts shard (deleting it's other copy).
- Local node gets a cluster state with the shard started in it, which cause it to send a shard failed (to make the master aware).
- Shard is failed and can't be re-assigned due to the allocation filter.
The recoverWhileUnderLoadWithNodeShutdown is also adapted a bit to fit the current behavior of allocation filtering (in the past it used to really shut down nodes). Last, all tests in that class are given better names to fit the current terminology.

Today we simply fetch the shards metadata without verifying the
index UUID the shard belongs to. We recently added this UUID
to the shard state metadata. This commit adds verification
to the shard metadata fetching to prevent bringing shards
back into an index it doesn't belong to due to name collisions.
Note, Jackson 2.5 is less lenient when it comes to not starting an object before starting to add fields on a fresh builder, fixed where applicable.

Sometimes, when using transport client for example, through a load balancer, there is a need to send a scheduled ping message to keep each channel alive.
Add support for `transport.ping_schedule`, which controls the schedule (-1 for disabled) at which a ping message will be sent. For transport client case, it gets enabled automatically since almost always this is the desired behavior.
We use the same 6 bytes header format for the ping message, with ES header and -1 for data length for ping message, and simply continue to process the next messages once this is encountered.
