Tested the series with a VM and a container and it worked as was
expected for both. Tested that guest-fsfreeze=0 correctly overrides
fs-freeze-on-backup too and checked that all the log messages appear for
backups, clones, and snapshots with vmstate=0. 

Didn't have a cluster ready today where I could check whether the option
is also correctly checked for replication too, but I'll see that I get
to that tomorrow.
