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.
bootstrap fall back to the **title** tag behavior. Bootstrap tooltips need to be activated. E.g. traditionally you may add something like:

```
<script type='text/javascript'>
	$(document).ready(function() {
		$("body").tooltip({ selector: '[data-toggle=tooltip]' });
	});
</script>
``` 
It is probably better to add a custom directive - e.g. something like this: http://jsfiddle.net/5ww8e/1/
Or use Bootstrap UI for Angular.
