Connects to ros2/rmw#320

Given a QoS profile and set of endpoints for the same topic, overwrite any policies set to
BEST_AVAILABLE with a policy such that it matches all endpoints while maintaining a high
level of service.

Add testable functions for updating BEST_AVAILABLE policies,

  • qos_profile_get_best_available_for_subscription
  • qos_profile_get_best_available_for_publisher

and add convenience functions that actual query the graph for RMW implementations to use,

  • qos_profile_get_best_available_for_topic_subscription
  • qos_profile_get_best_available_for_topic_publisher

If users set a policy as 'best available', then the middleware will pick a policy
that is most compatible with the current set of discovered endpoints while maintaining
the highest level of service possible.

For details about the expected behavior, see connected changes:

- ros2/rmw#320

Found some minor questions but I can not find a single error in the logic. Test suite is great.

Basically, ignore best available policies by overwriting them with the default policy used for services.
