Title:
Deleting a flavor can cause servers/detail to return HTTP 400
Status in OpenStack Compute (Nova):
Invalid
Bug description:
Steps to reproduce on essex-4:
1. Boot an instance using flavor ID 1
2. After the instance is active, delete the flavor (nova-manage flavor delete
m1.tiny)
3. Make a call to /servers/details (ie nova list)
# nova list
The server could not comply with the request since it is either malformed or
otherwise incorrect. (HTTP 400)

Either users should be blocked from deleting a flavor until all
instances booted from it terminate, or this should be more robust (I'd
propose the latter).
