Public bug reported:
[Impact]
Heat uses 'scheduler hints' to instruct the cloud that some resources
need special treatment, for instance that two cinder volumes have to be
created on different backends.
Without this patch, cinder client is broken and hints aren't properly
formatted leaving without effect the hints sent.
[Test Case]
Use script test_scheduler_hints.py against cinder API v2, the request
sent will contain "scheduler_hints": {"same_host": "SOME_ID"} while the
service expects "OS-SCH-HNT:scheduler_hints": {"same_host": "SOME_ID"}
An example output can be found in the file test_scheduler_hints.log
[Regression Potential]
No regression expected. Currently the key is being discarded by the
service and this patch just format it properly
