Create '/metrics' endpoint for otter.

 - Add a route, model method, and cql query.
 - This includes a test for the return value from the cassandra model.
 - '__init__.py' import required for route to be loaded.
Add missing colon in config.json.
Endpoint correctly setup to return a response.

The function was missing the 'with_transaction_id' decorator, and the
cql call was missing an required empty dictionary.
Enable 'make mockrun' to actually run.

'make mockrun' fails when *scheduler* and *mock* is set in the config.
This is because the scheduler setup requires that *cassandra_cluster*
has been set before hand, and this does not happen when running with
'--mock'.
Mock model method for get_metrics.
Otter Admin Application Setup

- Service setup, and options very similar to base otter app.
- Make commands for running admin with and without a mock backend
- Import of the Klein app so that the routes are registered
- Base route '/' that returns nothing. Ability to verify service
  available, and may be changed later to return relevant data.
started one-group table
resurrected row check in all viewing places

I think this is done. Just need to test. Also deleted group_state and launch_config tables schema
all cql statements end with semi-colon
some tests updated - they are working
Correcting test mistake done in earlier commit - reverting

where the test should check for dict but was checking for string (like earlier)
Got CassScalingGroupTestCase working

fixed code related to these tests

TODO: get CassScalingScheduleCollectionTestCase and CassScalingGroupTestCase working
Fix cass model test to reflect previous fix.

The previous fix was for a missing dictionary being passed to
CQLClient.execute.
CassScalingScheduleCollectionTestCase working
Test for get_metrics on a mocked model.
Initial implementaiton of an in memory undo stack.
Fix lint and add a verifyObject test.
Simple integration of undo stack with launch_server workflow.
Pass undo stack through the supervisor to launch_server.  Supervisor will rewind the stack if launch_server fails.
Fix lint.
