XD-2094 XD Cluster view

- Add `containers` tab
  - this renders the contents of `cluster/containers` REST endpoint
  - update the containers info with
     - groups
     - deployed modules
       - if the management port/jolokia are enabled, then deployed modules
will also display message rates which can be configured via property in
routes.js `$rootScope.enableMessageRates`
     - `shutdown` option if the management port is enabled
- Add tooltip on container and deployed modules values to display
container and deployment properties respectively.
Looks like the tool-tip is not working
