fixes #7598 - Docker - initial ui chgs to support CRUD

This is the initial commit to enabled create/review/update/delete of
docker repositories from the UI.

We may need to alter the behavior of some of the repository
info details (e.g. Published At), once we see how the content
is published and becomes available to consumers.

refs #7124 - docker - downcase pulp_id when creating docker repository

Unfortunately, docker requires that repository names do not contain capital
letters.  More specifically, it currently requires that they consist of [a-z0-9-_.]+.

The pulp_id is currently constructed of the labels from org, env, view and
repo.  The label currently follows the rule, with the exception that capital
letters are supported; therefore, this commit will downcase the pulp_id
for docker repos.
