The aim of this change is to prevent many identical requests to create
watcher index templates being submitted when a cluster first starts up
and many cluster state updates are happening. Prior to this change, if
watcher's original index template creation requests queued up behind other
cluster state change requests then for each other request watcher would
re-request creation of all its index templates. After this change it
uses a strategy similar to that used by ML to only have one creation
request per index template in the cluster state change queue at any time.

Although the job stats for jobs with missing results indices are clearly
ruined, it's better to provide zeroes for the missing values and show the
stats for other jobs than to fail the whole request. This means the UI
can continue to function.

Original commit: elastic/x-pack-elasticsearch@1f0c9fbb86
When a user executes a watch and specifies it as part of the
execute watch API, no triggered watch is created, as the watch
cannot be picked up anymore (it only leaves for the duration of
the request).
However until now the TriggeredWatchStore was invoked and tried
to delete this non-existing triggered watch, resulting in some
log cluttering.
This commit removes this try to delete a non-existing triggered
watch.

This is just the culmination of all of the minor PRs associated with 1068. It will:
- Drop the `.monitoring-data-N` index
- Drop use of `_type` in all cases (replaced by `doc` and a new `type` field)
- Drop the API version from the template name (e.g., instead of `.monitoring-es-6` we now use `.monitoring-es`).
- Change API version to `-6-` from `-2-`.
- Both exporters handle versioned resources (templates, pipelines, and watches)
- HTTP exporters will optionally (true by default) publish placeholders for the old, `-2` templates.
When this is backported, it will need to:
- Change `index_patterns` to `template` within the templates.
- Downgrade the version requirements for the templates, pipeline, and watches _and_ the HTTP exporter itself (all require 6.0)
This is a companion to the feature branch in X-Pack Kibana elastic/x-pack-kibana/pull/1318 and they need to be merged at the same time.
Original commit: elastic/x-pack-elasticsearch@6031cfffa4
This commit adds better security for scroll requests in that they are now tied to a single user as
we only authorize the request that creates the scroll. This is accomplished by adding a
SearchOperationListener that listens for new scroll contexts and stores the authentication on the
ScrollContext. Then upon
retrieval of the search context for a query or fetch, the current authentication is compared to the
authentication that was present when the scroll context was created. If the current authentication
belongs to a different user, then a SearchContextMissingException will be thrown to prevent leaking
a valid vs invalid scroll id.
Additionally, signing of a scroll id is only performed when there is a older node in the cluster
that would expect the scroll id to be signed. Once this is backported to 5.x, we can remove this
bwc layer for 6.0/master.

When a user or client intend to delete a datafeed
and its job, there is benefit into ensuring the
datafeed has gracefully stopped (ie no data loss).
In constrast, the desired behaviour is to stop and
delete the datafeed as quickly as possible.
This change adds a force option to the delete
datafeed action. When the delete is forced,
the datafeed is isolated, its task removed and,
finally, the datafeed itself is removed from the
metadata.

We try to install empty ML metadata as soon as possible after startup
if none exists. However, this still leaves a short gap when the cluster
is active with no ML metadata. To avoid problems, functions that use
the ML metadata should treat this situation as equivalent to having
empty ML metadata.

ignoreAliases allows to resolve index expressions against concrete indices only, rather than against indices and aliases. It is used for now only in IndicesAliasesRequest and the indices resolution code in the security plugin needs to be adapted accordingly.
Original commit: elastic/x-pack-elasticsearch@ae964eade9
This commit switches over to two index aliases per job: one for reading
and one for writing. In the future this will allow the addition of a
rollover endpoint for ML results indices. (Rollover is still not possible
following this change, but the change to make it possible in the future
should not be a breaking change now.)

The cluster state listener to decide if watcher should be reloaded was
assuming that no aliases could be used and thus wrongly could trigger
a reload, which could have lead to wrong test results.
During debugging I also added a reason for reloading and fixed another
wrong test assumption.
Also the listener does not rely on previous cluster state, but stores this
in instance variable, as we need to compare with local state and not the
previous cluster state.

This avoids log spam about being unable to create new mappings in indices
that are set to only allow one type. (It doesn't actually have any effect
on the deletion, which was working before despite the failure to create new
mappings for the legacy types referenced by the delete request.)

Because:
1. It's pointless, as new detector_index values are assigned when an
analysis_config is parsed
2. It creates a backwards compatibility issue when upgrading from v5.4
Original commit: elastic/x-pack-elasticsearch@2f61aa457e
This is the x-pack side of the removal of `accumulateExceptions()` for both `TransportNodesAction` and `TransportTasksAction`.
There are occasional, random failures that occur during API calls that are silently ignored from the caller's perspective, which also leads to weird API responses that have no response and also no errors, which is obviously untrue.
Original commit: elastic/x-pack-elasticsearch@9b57321549
Detectors now have a field called detector_index. This is also now the
field that needs to be supplied when updating a detector. (Previously
it was simply index, which was confusing.)
When detectors are added to an analysis_config it will reassign
ascending detector_index values starting from 0. The intention is
never to allow deletion of detectors from an analysis_config, but
possibly to allow disabling them in the future. This ensures that
detector_index values in results will always tie up with detector_ids
in the detectors that created them.

At the end of the test, LocalExporterTests checks if no more monitoring
data are exporter by checking multiple times the last time nodes_stats
documents were exported, stopping after 10 seconds. It does this in a
@After annotated method but it would be better to do this in a finally
block. Also, it should search for node_stats documents only if the
monitoring indices exist and are searchable to avoid some "all shards
failed" failures.

The kibana user role in mixed cluster test expects a old cluster test to have run first that would
disable the kibana user, but that test is not executed on 5.1.1 and prior versions. This change
makes a update request an upsert to account for this.
