The request can be either one of these two forms:
DELETE /v2/accelerator_requests?arqs=uuid1,uuid2,...
DELETE /v2/accelerator_requests?instance=uuid
The second form is idempotent, i.e., it would have the same effect
if called repeatedly with the same instance UUID. In other words,
it would not raise an error on the second and later attempts even if
the first one has deleted the ARQs. Whereas the first form is not
idempotent: if one or more of the ARQs do not exist, it would raise
an error. Nova uses the second form: so repeated calls do not cause
issues.
