By design, rolling content views do not have associated Pulp repositories.
This means it is not possible to push containers to them.

This is fine, because there is nothing preventing users from pushing their containers to a normal content view instead.
However, we need to make sure that attempting to push a container to a rolling content view results in a meaningful error message explaining this.

Something like: "It is not possible to push containers to rolling content views, please use a normal content view instead."

The scope of this ticket is to ensure that any attempt to push containers to a rolling content view, will result in this message and no change to the rolling content view.
