Goal: 

QE needs to write new test or add test steps to an existing test for testing of snapshot creation.

Acceptance Criteria:
We have tests for the actions listed as Acceptance Criteria in https://issues.redhat.com/browse/HMS-1446

• After creating a repository, if snapshotting is turned on for it, the repository is automatically snapshotted, and available at some url, which can be retrieved by the user
• Every night, a new snapshot is created if there is a change and available at some url, which can be retrieved by the user
• When a repository url is updated, the next nightly snapshot will be made using that new url
• When a repository is deleted, the snapshots will no longer be available.
