share server migration check does not allow replicas

[chuan137]

Hi,

share API does not allow migration to continue if any share has replicas. Afaik, some driver started supporting this feature now, e.g., NetApp OnTap 9.12 onwards. Would be nice to allow skipping the check in
_migration_init_check() [1] based on the driver's capability or configuration. Wdyt?

Best,
Chuan
