When the VIM Stragegy API returns a 409 Conflict for a create,
it is much more useful to know details about the conflict.
ie: what type of strategy already exists.
This fix required:
- the strategy creation rpc message adds an error string
- pecan.abort 'conflict' must include the error string
- the nfv_client code must extract the error string
- the strategy types must return knowledge of an existing
strategy type
- the director class must include details of the existing
strategy type in its failure messages.
Test Plan:
PASS: Create two patch strategies and view the error.
PASS: Create two different strategies and view the error.
PASS: View errors when creating multiple strategies
from horizon.
