[RHV] Importing a replicated storage domain in disaster recovery site fails with a "Cannot acquire Lease" sanlock error

Issue

• In a disaster recovery test we have replicated all LUNs to a secondary site.
• With the primary site powered off, we try to import one of the replicated storage domains in the destination site.

• The storage domain import fails with the error:

  2024-05-25 12:38:12,836+0200 ERROR (jsonrpc/4) [storage.dispatcher] FINISH forcedDetachStorageDomain error=Cannot obtain lock: "id=aaaaaaaac-bbbb-cccc-dddd-eeeeeeeeeeee, rc=-243, out=Cannot acquire Lease(name='SDM', path='/dev/aaaaaaaac-bbbb-cccc-dddd-eeeeeeeeeeee/leases', offset=1048576), err=(-243, 'Sanlock resource not acquired', 'Lease is held by another host')" (dispatcher:66)
  

• We would expect that the lease will expire in a few minutes after the original SPM host is off, however after ~20 minutes the same error is still happening.
