switch to nova_flavor provider

[Alex Schultz]

The upstream nova module added a nova_flavor provider as part of the newton cycle. https://review.openstack.org/#/c/305463/. We should update our management of nova flavors to leverage this provider.

For example we have this exec that should be replaced with a nova_flavor call:

    Update m1.micro flavor creation

    This change reworks how we are managing the m1.micro flavor that is used
    by OSTF. As part of this change we are moving the creation out of the
    general controller configuration and putting it into the task where we
    also manage the image installation used by OSTF. As part of this move,
    we are also refactoring the haproxy wait configuration for the nova
    backends to their own class with tests so it can be more easily reused.
