Joshua Boniface 4ef5fbdbe8 Restore previous autobackup continue behaviour 
With the original system, the failure of one VM's backups would not
trigger a total fault, thus allowing other backups to complete.
Restore that behaviour.

Joshua Boniface f1668bffcc Refactor autobackups to implement vm.worker defs 
Avoid trying to subcall other Celery worker tasks, as this just gets
very screwy with the stages. Instead reimplement what is needed directly
here. While this does cause a fair bit of code duplication, I believe
the resulting clarity is worthwhile.

Joshua Boniface 0d918d66fe Port VM autobackups into pvcworkerd with snaps 
Moves VM autobackups from being in-CLI to being handled by the
pvcworkerd system on the primary coordinator. Turns the CLI autobackup
command into an actual API client endpoint rather than having its logic
in the CLI.

In addition, modifies the new autobackup to leverage the new "pvc vm
snapshot" function set, just with special snapshot names. This helps
automate this within the new snapshot scaffolding.

Joshua Boniface f6c009beac Allow overriding stages in some commands 
This allows them to be called by autobackup commands while still
preserving the current Celery report flow.

Joshua Boniface 0bf9cc6b06 Improve stage handling 
Run start() at the beginning, and leverage the new tweaks to the CLI to
update the total steps later. Allows errors to be handled gracefully

Joshua Boniface 8937ddf331 Simplify VM rename to preserve data 
A rename is simply a change to two values, so instead of undefining and
re-defining the VM, just edit those two fields. This ensures things like
snapshots are preserved automatically.

Joshua Boniface 5d0e7931d1 Add support for rolling back snapshots 
We supported creating snapshots, but not doing anything with them. This
removes the manual task of restoring a snapshot and replace it with a
PVC abstraction of rolling back to a snapshot.

While Ceph recommends cloning a snapshot instead of rolling back, due to
the time taken, in our usecase I don't think that is an optimal
strategy, as it will leave dangling clones that we'd then have to
manage.

Closes #183

Joshua Boniface a95e72008e Add size validations for volume clones 
Adds the same validations as a volume add or resize to volume clones, to
ensure there is enough free space for them.

Joshua Boniface efc7434143 Add safety check for 80% full size 
Adds a check that a volume creation or resize won't violate the 80% full
rule for the storage cluster. This ensures a cluster won't get too full
if a storage volume fills up.

Also adds a force flag throughout the pipeline to override this check,
should an administrator really want to do so.

Joshua Boniface 8419659e1b Ensure zkhandler is always cleaned up 
Even if the subfunction of an API @ZKConnection call fails, the
zkhandler needs to terminate and clean up, or it leaves stuck threads
around.
