Add SUSE support in mysql datastore

SUSE uses /etc/my.cnf instead of /etc/mysql/my.cnf. This patch changes
MYSQL_CONFIG from string to a dictionary using the operative system
name as key to identify where mysql's configuration is located.

Stop using intersphinx

Remove intersphinx from the docs build as it triggers network calls that
occasionally fail, and we don't really use intersphinx (links other
sphinx documents out on the internet)

This also removes the requirement for internet access during docs build.

This causes docs jobs to fail because we error out on warnings.

Event simulator II

The previous event simulator simulated time by making all tasks that
would have been launched as threads run in the same thread. That only
worked to a point but didn't properly simulate more complex behaviors
such as clustering.

This new one handles things properly by still running tasks in
eventlet's greenthreads but forcing them to only run one at a time.

Removing dependency on trove models in the guest agent

Reasons:
 - The guest agent is importing backup models and agent
   heartbeat, this triggers the all of the trove database
   setup logic which bloats the guest process on the host.

 - Moving the state to its own module and removing an unused
   function decreases the memory usage by about 15 - 20 megs.
