* endpoint/api/repository: limit the number of tags returned
- Limit the number of tags returned by /api/v1/repository/<ns:repo> to 500.
- Uses the tag history endpoint instead, with an active tag filte.
- Update UI to use tag history endpoint instead.
While this means we need an additional query for initial lookup, it makes the *filtering* query (which is the heavy part) require far fewer joins, thus making it more efficient.
Also adds a new unit test to verify that our filter filters to the correct set of repositories.
Only verbs needs to load placements for multiple images, so we can vastly simplify and optimize most queries by making it two-step, and having the rest of the image loads not worry about placements
Instead of deleting a namespace synchronously as before, we now mark the namespace for deletion, disable it, and rename it. A worker then comes along and deletes the namespace in the background. This results in a *significantly* better user experience, as the namespace deletion operation now "completes" in under a second, where before it could take 10s of minutes at the worse.

MySQL does not allow rows in the same table referencing other rows to be deleted in a single statement. We now do a two-pass deletion, and add a test to make sure.

Teams can now have a TeamSync entry in the database, indicating how they are synced via an external group. If found, then the user membership of the team cannot be changed via the API.
Previous to this change, repositories were looked up unfiltered in six different queries, and then filtered using the permissions model, which issued a query per repository found, making search incredibly slow. Instead, we now lookup a chunk of repositories unfiltered and then filter them via a single query to the database. By layering the filtering on top of the lookup, each as queries, we can minimize the number of queries necessary, without (at the same time) using a super expensive join.
Other changes:
- Remove the 5 page pre-lookup on V1 search and simply return that there is one more page available, until there isn't. While technically not correct, it is much more efficient, and no one should be using pagination with V1 search anyway.
- Remove the lookup for repos without entries in the RAC table. Instead, we now add a new RAC entry when the repository is created for *the day before*, with count 0, so that it is immediately searchable
- Remove lookup of results with a matching namespace; these aren't very relevant anyway, and it overly complicates sorting
