Add a "clean" state to redhat_manifest

[parmstro]

SUMMARY

When refreshing a manifest as subscriptions change, we want to be able to be deterministic about the list of subscriptions attached to a manifest. We also may not want to change the manifest uuid by deleting and recreating the manifest. The manifest module does not implement a manifest_info module (it should) to allow us to determine the list of subscriptions currently attached to the manifest. We should be able to make a call to clear all existing subscriptions from the manifest. Then re-add the list of subscriptions that we want.

(In fact, one could argue that modules should have a corresponding _info module by default)

Wait, which manifest module? The subscription manifest one that talks to Katello/Satellite or the redhat manifest one that talks to the portal?
