The start scheduler waits until the scheduler state has been set to started before returning.
Before this change after the scheduler state has been set to started, the scheduler would link itself to the task the start scheduler api has created.
If the stop scheduler api was called immediately after the start scheduler api then this could lead the stop scheduler api cancelling the task without
stopping the scheduler, as the scheduler could not have been linked to the task.
Now the scheduler gets linked to the task before the scheduler state is set to started, fixing the problematic situation discribed above.

Also merged the JobProvider#getBucket(...) method into Jobprovider#getBuckets(...) method, because
it contained a lot of similar logic, otherwise it had to be converted to use non blocking client calls too.

There was an N-squared algorithm in the state processing code, leading
to large state persistence eventually timing out. Large state documents
are read from the network in 8KB chunks, and the old code was checking
ALL previously read chunks for separators every time a new chunk was read.

Deleting a job now starts a three-step process:
1. Job status updated to DELETING
2. Physical index is deleted
3. Job removed from cluster state
When jobs are in DELETING, they cannot be modified/updated/changed at all. Only jobs that are DELETING can actually be removed from the CS.

with the fix we also make sure that prelert metatadata is taken into account when verifying the cluste state consistency

Note that the change in elasticsearch allowed us to store scheduler
config's query and scriptFields as typed objects instead of
ByteReference.

* Check the bulk request contains actions before executing.
This suppresses an validation exception about no requests being added.
* Persist bulk request before refreshing the indexes on a flush acknowledgment

* Strict parse search parts of schedulerConfig
This commit adds methods to build the typed objects
for the search parts of a scheduler config. Those are:
query, aggregations and script_fields.
As scheduler configs are stored in the cluster state and parsing
the search parts requires a SearchRequestParsers object, we cannot
store them as typed fields. Instead, they are now stored as
BytesReferences.
This change is in preparation for switching over to using a
client based data extractor.
Point summary of changes:
- query, aggregations and scriptFields are now stored as BytesReference
- adds methods to build the corresponding typed objects
- putting a scheduler now builds the search parts to to validate that
the config is valid

This doesn't happen initially when buckets are output by the C++, but
buckets can contain records at the moment they're sent for persistence
during normalization or during integration tests. It's safest if the
persistence code specifically doesn't persist these records.

* Add job config option to set the index name
* Check index does not already exist if ’index_name’ is set
* Don’t create alias if ‘index_name’ is the same as ‘job_id’
* Default index_name value
Set it to job_id if null and only create the index alias if job_id != index_name
* Fix compile errors after rebasing
* Address review comments
* Test if the index exists by checking the cluster state
* Update comment
