The method to check if watcher was enabled was returning
`randomBoolean()` and thus could change during test runs.

As there are two indices to upgrade for watcher, it makes a lot of sense
to also have two upgrade checks.
There is one upgrader for the watches index, which deletes
old templates, adds the new one before and then does the reindexing.
Same for the triggered watches index.
This also means, that there will be two entries popping up in the kibana
UI.
Note: Each upgrade check checks if the other index (for the .watches
upgrade check the triggered watches index and vice versa) is already
upgraded and only if that is true, watcher is restarted.

Original commit: elastic/x-pack-elasticsearch@2c92040ed6
I noticed this while working on a previous issue with atomic move writer
(silent swallowing of exceptions). Namely, atomic move writer has
dangerous semantics. The problem is as follows: atomic move writer works
by writing lines to a temporary file, and then in its close method it
replaces the target path with the temporary file. However, the close
method is invoked whether or not all writes to the temporary file
succeeded (because writers obtained from atomic move writer are used in
try-with-resources blocks, as they should be). There is no way to
distinguish that the writer is being closed in a successful scenario
versus a failure scenario. In the close method for atomic move writer,
the target file is replaced by the temporary file. This means that the
target file is replaced whether or not writing to the temporary file
actually succeeded. Since these atomic move writers are used for user
configuration files (users and user_roles), a failure here can lead to
data loss for the user, a tragedy!
There is another (less serious) problem with the atomic move
writer. Since the close method tries to move the temporary file in place
of the existing file, the temporary file can be left behind if there is
another failure in the close method (e.g., closing the underlying file
after writing, or setting the permissions on the temporary file). This
means that in some situations, atomic move writer will leave temporary
files behind (which is not definitively not atomic).
This commit replaces the atomic move writer with a safer mechanism. We
still perform the write atomically in the following sense: we write to a
temporary file. Either writing to that file succeeds or it fails. If
writing succeeds, we replace the existing file with the temporary
file. If writing fails, we clean up the temporary file and the existing
file remains in place.

Original commit: elastic/x-pack-elasticsearch@3a52bad460
When a watch is executed currently, it gets passed an in-memory
watch object, that was loaded, before the execution started.
This means there is a window of time, where an old watch could still
be executing, then a watch gets loaded for execution, then the old watch
execution finishes and updates the watch status and thus reindexes the
watch.
Now the watch, that got loaded for execution, executes and tries to
store its watch status, but fails, because the version of the watch
has changed.
This commit changes the point in time where the watch is loaded. Now
this only happens, while a watch is in its protected execution block,
and thus we can be sure, that there is no other execution of the watch
happening.
This will primarily impact watches, that execute often, but their
runtime is longer than the configured interval between executions.
Side fix: Removed some duplicate testing method and moved into
WatcherTestUtils, fixed a tests with a ton of if's with random booleans
into separate tests.

Today we require a pre-shared key to use the token service. Beside the
additional setup step it doesn't allow for key-rotation which is a major downside.
This change adds a TokenService private ClusterState.Custom that is used to distribute
the keys used to encrypt tokens. It also has the infrastructur to add automatic key
rotation which is not in use yet but included here to illustrate how it can work down
the road.
This is considered a prototype and requires additioanl integration testing. Yet, it's fully
BWC with a rolling / full cluster restart from a previous version (also from 5.6 to 6.x)
since if the password is set it will just use it instead of generating a new one.
Once we implement the automatic key rotation via the clusterstate we need to ensure that we are
fully upgraded before we do that.
Also note that the ClusterState.Custom is fully transient and will never be serialized to disk.

Today we try to bootstrap the security index with the bootstrap password and recommend the user to change the password with the user tool. This is trappy for instance if you happen to configure multiple nodes with a different bootstrap passwords (which is possible) it's unclear which password made it too bootstrap. Yet, we tell in the logs but it can still be very confusing. In general it should be possible to bootstrap with the user tool from any node unless the user is already created in the native user store. This change uses the bootstrap.password from the local node and always authenticate against it until the user is bootstrapped even if the passwords are different on different nodes. This will also work for authenticating against the cluster for instance if a user deletes the .security index or if that index has not been upgraded.
Original commit: elastic/x-pack-elasticsearch@8cebecb287
When writing the users and users_roles files, we wrap a custom writer in
a print writer. There is a problem with this though: when print writer
closes it closes our underlying custom writer and the close
implementation for our custom writer is not trivial, it executes code
that can throw an I/O exception. When print writer invokes this close
and an I/O exception is thrown, it swallows that exception and sets the
status on the print writer to error. One would think that we could
simply check this status but alas print writer is broken here. The act
of checking the status causes print writer to try to flush the
underyling stream which is going to be completely undefined because the
underlying stream might or might not be closed. This might cause another
exception to be thrown, losing the original. Print writer screwed the
pooch here, there is no good reason to try to do any I/O after the
underlying writer entered a failed state. To address this we remove the
use of print writer, we use our custom writer directly. This allows any
thrown exceptions to bubble up.

These tests used to fail rarely, because during a watch execution
one of the watcher shards was relocated resulting in a second execution

In order to prevent this, the tests do not need to actually create any

When a watch is executed, it sends an update request to the watch to
udpate its status.
This update request also updates the status.state field, which contains
information, if the watch is active. If the watch gets executed, and
during execution a watch gets disabled, then the current execution will
set the watch back to active.
This commit fixes the current behaviour and never changes the state of
a watch when updating the status after executing, allowing
activate/deactivate calls to work as expected, regardless if a watch
is being executed.
This will fix not only the current behaviour but also some flaky tests.

This commit adds the max_running_jobs setting from elasticsearch.yml
into a node attribute called ml.max_open_jobs. Previously there was
an assumption that max_running_jobs would be the same for all nodes in
the cluster. However, during a rolling cluster restart where the value
of the setting is being changed this clearly cannot be the case, and
would cause unexpected/unpredictable limits to be used during the period
when different nodes had different settings.
For backwards compatibility, if another node in the cluster has not added
its setting for max_running_jobs to the cluster state then the old
(flawed but better than nothing) approach is applied, i.e. assume the
remote node's setting for max_running_jobs is equal to that of the node
deciding the job allocation.

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
