Feature: implement switch for scope host/pod
Implement a switch, to decide, weather certain elements act in host or pod scope. Default to pod.
For example:
- volume_machine vol:/path:opt -> vol:/path:opt
- volume vol:/path:opt -> pod_vol:/path:opt
- container dependencies...
(MOST OF OUR VOLUMES ARE CONFIGURED TO INCLUDE PODNAME BY HAND. THIS WILL CAUSE CONFLICT, IF FEATURE IS IMPLEMENTED RECKLESSLY)
