This PR adds a new field `RemoteAddress` to both mirror types which
contains the sanitized remote address for easier (database) access to
that information. Will be used in the audit PR if merged.

To solve the cyclic imports in a better way

Closes #20261

Allow users to edit the sync interval for existing push mirrors.
Currently, there is no way to modify the interval once the mirror is
created.
