Snapshot mirrors should normally be promoted using "mirror promote", and
not started manually. This adds guard rails against that to the "start",
"stop", and "disable" state commands to prevent changing mirror states
without an explicit "--force" option.
Adds two helper commands which automate sending and promoting VM
snapshots as "vm mirror" commands.
"vm mirror create" replicates the functionality of "snapshot create" and
"snapshot send", performing both in one single task using an
autogenerated dated snapshot name for automatic cross-cluster
replication.
"vm mirror promote" replicates the functionality of "vm shutdown",
"snapshot create", "snapshot send", "vm start" (remote), and,
optionally, "vm remove", performing in one single task an entire
cross-cluster VM move with or without retaining the copy on the local
cluster (if retained, the local copy becomes a snapshot mirror of the
remote, flipping their statuses).
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.
Adds a new flag to VM metadata to allow setting the VM live migration
max downtime. This will enable very busy VMs that hang live migration to
have this value changed.
Move the create_vm and run_benchmark tasks to use the new Celery
subsystem, handlers, and wait command. Remove the obsolete, dedicated
API endpoints.
Standardize the CLI client and move the repeated handler code into a
separate common function.
