The Clock interface, which basically allows testing in watcher to "time
warp" is currently constructed using guice. This change constructs it
using a protected method on XPackPlugin which can be overriden in tests.
This allows removing the ClockModule. For now, the Clock still needs to
be bound in guice, but this at least removes one guice construction, and
shows how other things can be overriden for tests.

This makes use of the registerAsDeprecatedHandler method to automatically warn users when they're using deprecated functionality.
This will also automatically provide a Warning header for anyone using HTTP clients (though they have to be looking for it...).

This adds the following stats to the usage stats
* Across all active watches
* Number of triggers per type
* Number of inputs per type
* Number of transforms per type
* Number of conditions per type
* Number of actions per type
* Total number of watches
* Total number of active watches
* Per action
* Execution time total
* Execution time mean
* Invocation count
* Total use of watch metadata
Internally this uses a `Counters` helper class, so that creating counters does not require
you to decide about the map structure.

This changes the way that Kibana (and future applications) send their monitoring stats to Elasticsearch.
Instead of sending their payloads with the System ID (e.g., "kibana") and System Version (e.g., "5.0.0-alpha4"), it now expects the System ID and System _API_ Version (e.g., "2"). This means a few things:
- Future releases are automatically compatible with previous releases as long as the API version doesn't change.
- Users don't have to update Kibana at the exact same time as their cluster (which technically means rolling updates were temporarily blockers of Kibana monitoring before).
- We can accept old API versions (if we need to make a breaking change) and automatically up-convert them to the latest API version. (We are in full control of how far back we choose to accept)
In general, this change implies that users should be updating their Monitoring cluster before their _monitored_ cluster(s) to get the best opportunity of monitoring backwards compatibility. That way if any API change does occur, then it can up-convert as needed. Then, any ES node should be updated, and only then should Kibana be updated. This is not required in any way, but it will give the smoothest experience.

While testing another PR, I noticed that when Security is disabled, the _xpack/usage API throws a NullPointerException.
This checks for null before using it, and adds tests to verify behavior.
Original commit: elastic/x-pack-elasticsearch@6474af6569
When a painless exception is raised in the script condition, it was not bubbled up due to
catching exceptions on during execution. This removes the different catching of exceptions
and allows the watch record construct to contain an exception that is also serialized correctly
so that it can be stored in the watch history but also returned in the execute watch API.
This also updates the watch history template, so that exceptions are not indexed, but logged.

The top-level class Throwable represents all errors and exceptions in
Java. This hierarchy is divided into Error and Exception, the former
being serious problems that applications should not try to catch and the
latter representing exceptional conditions that an application might
want to catch and handle. This commit renames
org.elasticsearch.cli.UserError to org.elasticsearch.UserException to
make its name consistent with where it falls in this hierarchy.

Original commit: elastic/x-pack-elasticsearch@589e159ec0
Today throughout the codebase, catch throwable is used with reckless
abandon. This is dangerous because the throwable could be a fatal
virtual machine error resulting from an internal error in the JVM, or an
out of memory error or a stack overflow error that leaves the virtual
machine in an unstable and unpredictable state. This commit removes
catch throwable from the codebase and removes the temptation to use it
by modifying listener APIs to receive instances of Exception instead of
the top-level Throwable.

Original commit: elastic/x-pack-elasticsearch@7ecdd7d978
This looks like it predates settings validation in core, and only had a
single use inside the watcher ExecutionService. This change moves the
settings inside ExecutionService to be validated settings, and removes
the watcher specific validation.
