    METRON-982 add new rest api for storm supervisor status

    This pr adds a new rest endpoint for retrieving storm supervisor summary information from the "/api/v1/supervisor/summary" storm ui rest endpoint.
    
    This information contains the currently configured slots for each supervisor, and how many are used.
    
    This is in support of METRON-981, which will be able to use this endpoint to enable errors and warnings based on the lack of available slots.
    
    ###TESTING
    
    In full_dev environment execute the new endpoint from swagger, you should see the supervisor information from storm
    
    /supervisors  off of the storm controller
