runtime-rs: Add idempotency to hotplug block device operations

Browse Source

Due to the lack of atomicity in the operation, a partial failure can
lead to an inconsistent QEMU state, which pollutes subsequent
operations. This can easily trigger a "Duplicate nodes" error. To
prevent this, we should query the state before performing the operation.
ee should ensure its validation and idempotency when making the function
idempotent allows it to be safely retried.

Fixes #11649
