This commit enhances job/datafeed APIs that support acting
on multiple jobs/datafeeds at once so that they accept
expressions that may contain comma-separated lists or
wildcard patterns.
The APIs that are enhances are:
- get jobs API
- get job stats API
- close job API
- get datafeeds API
- get datafeed stats API
- stop datafeed API

If the native controller dies or is killed then requests to open jobs
now immediately return with an error that says what the problem is.
The error that is logged also now clearly records the problem.
Previously open job requests would time out if the native controller
was not running, and logged errors were not easy to understand without
in-depth knowledge of the ML code.

This commit proposes removing an unnecessary directory push/pop from the
X-Pack scripts. It is not clear exactly why these were added, the
original change was almost three years ago in
elastic/x-pack@ea9ba7cdd0 but
unfortunately the commit message does not elucidate the exact the
problem, nor is there an associated pull request. This change has
propogated into all of the X-Pack scripts yet still the reasons are
unclear. The little that we can glean from the commit message is that
there was a problem with the default paths if the script was executed
outside of the Elasticsearch home. It seems that such issues have been
addressed by the recent introduction of elasticsearch-env so maybe we
can simplify these scripts here?

on Windows, if these scripts exits due to an error (e.g., Java can not
be found, or the wrong version of Java is found), then the script
exits. Sadly, on Windows, this does not also terminate the caller,
instead returning control. This means we have to explicitly exit so that
is what we do in this commit.

The full cluster restart tests are currently geared towards the 5.6 -> 6.0 upgrade and have some

To achieve backwards compatibility the easiest way is
to restore the old watcher stats, which are supposed to run

The distributed watcher stats have been moved under the statsdist
package and the action name has been changed as well.
This way there is no need to have a serialization BWC layer,
we can just call different actions.
Note: With the current approach developers still need to change
their java applications if they try to receive watcher stats,
as by default we are now using the distributed stats in the
watcher client.

Closing jobs can still use some or all of the threads that communicate
with the C++ process - the number of threads used will decrease as the
close progresses, but at the beginning of the closure all are still in
use. Therefore, to prevent the risk of EsRejectedExecution exceptions
for the autodetect communications threadpool, closing jobs need to be
considered when checking that enough threads exist to start a new
process. An explicit check produces a much more understandable error
message than an EsRejectedExecution exception.

1. If a job hangs in the closing state for any reason there is now a

2. The force delete endpoint (as used by the UI) killed open jobs before

possibility that if a job was deleted from the UI while in the closing

This changes the SecurityTribeIT tests to use the same settings object when creating the settings
for the tribe node. Previously two different objects were being created and we would read regular
settings from one and secure settings from another. This causes problems since randomization means
that there may be settings added on the first call that do not get added on the second call. One
example is the randomization of when to only use a keystore or to use both a keystore and a
truststore. On the first call, we would add settings for both a keystore and a truststore but on
the second call only the keystore settings were added. This lead to failures as we would not be
able to open a password protected truststore since the password was never added to the secure
settings.

We are still lenient on dynamic reload because

(b) file writes aren't atomic, so we might be picking up a file that is half way through being written (etc).
If you rely on the default role mapping filename, then it doesn't need to exist (because you might be using the role mapping API instead) but if it does exist it has to parse successfully

The active directory user principal name format typically takes the form user@domain, which is what
the current implementation expects. However, active directory also allows the definition of other
suffixes that are not actual domains. A user can still authenticate using this user principal name
but the behavior of our realm would cause it to fail as it parsed the suffix as a domain and used it
as the search base for the user. Instead, we should use the default user search base and only look
for entries that have this exact user principal name. In a scenario where a realm is configured for
multiple domains in the same forest, the search base should be the base for the entire forest.

When having a mixed cluster with 5.6 and 6.0 nodes, the template upgrade
service has a cluster state listener that deletes the old watches and

The monitoring watches are roughly executing the same queries even when
they run against different clusters. However the way they were created,
where the cluster name is replaced via search & replace instead of using
watch metadata implies, that every watch is different from a script
compilation cache perspective. On top of that every of those watches is
executed once a minute. So if a new node becomes master and you monitor
three clusters, this results in a fair share of compilations in the first minute. The
reason for the compilation is the fact, that the search input uses
mustache for being able to add dynamic parts into a search using
mustache.
Several of those watches also need to compile more than one search
request.
The maximum default value for script compilations is only 15 and thus at
least one watch will not be executed due to failing script compilations.
This commit changes the four watches, so that the search requests are
cacheable. This means, no matter how many clusters you monitor, there
will be only needed four compilations for the different watches and
that's it.

ML has two types of custom cluster state:
1. jobs
2. datafeeds
These need to be parsed from JSON in two situations:
1. Create/update of the job/datafeed
2. Restoring cluster state on startup
Previously we used exactly the same parser in both situations, but this
severely limits our ability to add new features. This is because the
parser was very strict. This was good when accepting create/update
requests from users, but when restoring cluster state from disk it meant
that we could not add new fields, as that would prevent reloading in
mixed version clusters.
This commit introduces a second parser that tolerates unknown fields for
each object that is stored in cluster state. Then we use this more
tolerant parser when parsing cluster state, but still use the strict
parser when parsing REST requests.
