This integrates SQL's metadata calls with security by creating
`SqlIndicesAction` and routing all of SQL's metadata calls through
it. Since it *does* know up from which indices it is working against
it can be an `IndicesRequest.Replaceable` and integrate with the
existing security infrastructure for filtering indices.
This request is implemented fairly similarly to the `GetIndexAction`
with the option to read from the master or from a local copy of
cluster state. Currently SQL forces it to run on the local copy
because the request doesn't properly support serialization. I'd
like to implement that in a followup.

This shuffles all of SQL's QA tests into the `qa/sql` directory, moving
some shared resources into the new `qa:sql` project. It also rigs up
testing of the rest SQL interface in all the sql qa configurations:
without security, with security, and against multiple nodes.
I've had to make some modifications to how we handle the audit log
because it has gotten pretty slow. If these modifications turn out to
not be fast enough then I'll change the test to querying the log files
and drop the audit log index entirely but the index seems to be holding
out for now.
