Enhance the status query API

This patch enhances the status query API.
- The ResourceBundleState CRD is modified to just use the
  k8s Pod structure instead of a customized struct.
- Status queries can either present results showing
  the rsync status of the composite app and resources
  or from information received from the cluster via
  the ResourceBundleState CR
- Query parameters are provided to the API call to
  customize the query and response
- Support for querying status of cluster network
  intents is added
