Goal: 

• To support templates that use the latest snapshot, repository distributions within those templates must be updated every time a new snapshot is created.
• In a new task, after the repository snapshot task, fetch every use_latest template associated to that repository and update its distributions to point to the new snapshot.
• For custom repositories, filter by org ID. For red hat repositories, all templates can be updated.
• This new task should add the snapshot task as a dependency
• The taskinfo fetch and list queries should be updated to include the list of dependencies

Acceptance Criteria:

• An existing use_latest template's distributions should be updated when an associated repository gets a new snapshot
• A new task, that is dependent on the snapshot task, is created for making these template updates
• The new task doesn't run if the snapshot fails
• The tasks list and fetch APIs should include the task's dependencies
