Test report: PASS

(1) Create 2 similar backup for same VM:

got error:

admission webhook "validator.harvesterhci.io" denied the request: same granularity as schedule svmbackup-vm1-running and offset less than 10m0s

(2) Suspend a schedule and create a new one
got error:

admission webhook "validator.harvesterhci.io" denied the request: VM default/vm1-running already has backup schedule

(3) Create schedule type snapshot after an existing schedule type backup
got error:

admission webhook "validator.harvesterhci.io" denied the request: VM default/vm1-running already has backup schedule

(4) Change the backup source vm via Edit Yaml (not allowed from UI config directly)
got error:

admission webhook "validator.harvesterhci.io" denied the request: source vm can't be changed

(5) Disable the backup target to test the status of schedule
(5.1) Create a NFS type schedulebackup
(5.2) Stop the NFS server
(5.3) Wait until the schedule is triggered, then observe:

the above meets the expectation

(5.4) Start the NFS server
(5.5) Manually delete the error backup

(5.6) But the schedulebackup still shows below message

5.6 could be handled via #6876

A minor fix #6876 could be addressed in next release.
