Daniel P. Berrangé 9c3b2c9db5 qom: replace 'can_be_deleted' with 'prepare_delete' ...

While most objects can perform all their cleanup in the finalizer
method, there can be interactions with other resources / subsystems
/ threads which require that some cleanup be performed on an user
creatable object before unparenting it and entering finalization.

The current 'can_be_deleted' method runs in the deletion path and
is intended to be used to block deletion. While it could be used
to perform cleanup tasks, its name suggests it should be free of
side-effects.

Generalize this by renaming it to 'prepare_delete', explicitly
allowing for cleanup to be provided. Existing users of 'can_be_deleted'
are re-written, which provides them with more detailed/tailored error
messages.
