Fixes #6097,bz1120427 - repository.feed -> repository.url

Migrating a repository data model attribute from feed to url. The word
feed applies to the feed url used by pulp, but in katello UI, CLI and
API we consistently use url for feed. To mitigate this confusion it was
deemed to rename feed to url.

fixes #6547 / BZ 1115468 - delete puppet modules from content view on repo delete

When a puppet repository is deleted (e.g. from Content -> Products),
if any of the puppet modules in that repository are associated with
an existing content view (via ContentViewPuppetModule), they need
to be removed from the content view.  This commit will do just
that, providing a behavior that is consistent with when a user
deletes a yum repository (i.e those repositories are removed
from the content view).
fixes #6913 / BZ 1092143 - content view version - disable promote/remove on failed task

This commit will disable the promote/remove button for a content view version,
if the current task being executed resulted in in an error.  Once the error
has been resolved and the task completes, the buttons will be re-enabled.
