The provider driver utils module converts Octavia data model objects
to provider driver objects.
This module had some bugs in the conversion that led to errors and
incomplete data.
Specifically the following conversions were fixed:
flavor_id in load balancer conversion
sni_refs and L7 policies in listener conversion
health monitors in pool conversion
This patch corrects those and updates the tests.
