Takashi Kajinami 14f9b7627e Retry attachment delete API call for 504 Gateway Timeout 
When cinder-api runs behind a load balancer(eg haproxy), the load
balancer can return 504 Gateway Timeout when cinder-api does not
respond within timeout. This change ensures nova retries deleting
a volume attachment in that case.

Also this change makes nova ignore 404 in the API call. This is
required because cinder might continue deleting the attachment even if
the load balancer returns 504. This also helps us in the situation
where the volume attachment was accidentally removed by users.

Closes-Bug: #1978444

In the unfortunate event that bugs are discovered, they should be reported to the appropriate bug tracker. If you obtained the software from a 3rd party operating system vendor, it is often wise to use their own bug tracker for reporting problems. In all other cases use the master OpenStack bug tracker, available at:
