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.

This test creates watches in old versions of elasticsearch, upgrades them after upgrading cluster to the latest version and then tests that they were upgraded correctly.

This commit is related to elastic/x-pack-elasticsearch#1896. Currently setup mode means that the
password must be set post 6.0 for using x-pack. This interferes with
upgrade tests as setting the password fails without a properly
upgraded security index.
This commit loosens two aspects of the security.
1. The old default password will be accept in setup mode (requests
from localhost).
2. All request types can be submitted in setup mode.

This is step 2 of elastic/x-pack-elasticsearch#1604
This change stores `model_memory_limit` as a string with `mb` unit.
I considered using the `toString` method of `ByteSizeValue` but it
can lead to accuracy loss. Adding the fixed `mb` unit maintains
the accuracy, while making clear what unit the value is in.

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.

This is the x-pack side of https://github.com/elastic/elasticsearch/pull/24437
It changes two things, for the disable tests, it uses a valid endpoint instead
of a previously invalid endpoint that happened to return a 400 because the
endpoint was bad, regardless of if watcher was disabled.
The other change is to create the watches index by putting a watch using the
correct API, rather than manually creating the index. This is because
`RestHijackOperationAction` hijacks operations like this and stops accessing the
endpoint in a regular manner.

Currently, the autodetect process has an `ignoreDowntime`
parameter which, when set to true, results to time being
skipped over to the end of the bucket of the first data
point received. After that, skipping time requires closing
and opening the job. With regard to datafeeds, this does not
work well with real-time requests which use the advance-time
API in order to ensure results are created for data gaps.
This commit improves this functionality by making it more
flexible and less ambiguous.
- flush API now supports skip_time parameter which
sends a control message to the autodetect process
telling it to skip time to a given value
- the flush API now also returns the last_finalized_bucket_end
time which allows clients to resume data searches correctly
- the datafeed start API issues a skip_time request when the
given start time is after the resume point. It then resumes
the search from the last_finalized_bucket_end time.

Original commit: elastic/x-pack-elasticsearch@caa5fe8016
This fixes `testDeleteJobAfterMissingAliases` to not fail randomly.
The reason the test was failing is that at some point some aliases
are deleted and the cat-aliases API is called to verify they were
indeed deleted. This was checked by asserting an
index_not_found_exception was thrown by the cat-aliases request.
This was some times working as there were no other aliases. However,
that depends on whether other x-pack features had time to create their
infrastructure. For example, security creates an alias. When other
aliases had the time to be created, the cat-aliases request does not
fail and the test fails.
This commit simply changes the verification that the read/write
aliases were deleted by replacing the cat-aliases request with
two single get-alias requests.

The logging shows a wrong HTTP response status code from a previous
request. In addition the body now also gets logged, as debugging
is impossible otherwise.

This changes from collecting every index statistic to only what we actually want. This should help to reduce the performance impact of the lookup.

This is related to elastic/x-pack-elasticsearch#1217 and elastic/x-pack-elasticsearch#1896. Right now we are checking if an
incoming address is the loopback address or a special local addres. It
appears that we also need to check if that address is bound to a
network interface to be thorough in our localhost check.
This change mimicks how we check if localhost in `PatternRule`.

Depending on the random numbers fed to the analytics,
it is possible that the first planted anomaly ends up
in a different bucket due to the overlapping buckets feature.
Then that may result to a single interim bucket being available
due to overlapping buckets blocking the other interim bucket
from being considered.
I am removing the initial anomaly from the test as it is not useful
and it makes the test unstable.

This commit removes the system key from master and changes watcher to use a secure setting instead
for the encryption key.
Original commit: elastic/x-pack-elasticsearch@5ac95c60ef
This is related to elastic/x-pack-elasticsearch#1217. This PR removes the default password of
"changeme" from the reserved users.
This PR adds special behavior for authenticating the reserved users. No
ReservedRealm user can be authenticated until its password is set. The
one exception to this is the elastic user. The elastic user can be
authenticated with an empty password if the action is a rest request
originating from localhost. In this scenario where an elastic user is
authenticated with a default password, it will have metadata indicating
that it is in setup mode. An elastic user in setup mode is only
authorized to execute a change password request.

We made the mistake to generate way to many settings in xpack which makes
finding out the right string and where it's defined super difficult. If
we use constants we can just use commandline tools to find where the settings
are defined. This also removes 1.x and 2.x BWC from the enabled settings which should
be removed in 6.x
