summary: Check snap refresh hold and unhold
details: |
Check that running `snap refresh --hold` without specifying snaps prevents
auto-refreshes for a configurable amount of time (even indefinitely) but not
general refreshes (i.e., refreshes triggered by a `snap refresh` without
specifying arguments). Check that holding refreshes for specific snaps
prevents general refreshes as well as auto-refreshes but not specific snap
refreshes.
