Add API version check capabilities

This patch adds a method that allows us to get the current Designate API version under test for use in test classes to skip tests against new features introduced in a specific API version.
This patch also centralizes the "primary" zones client to be instantiated once and updates the tests to use a standardized name for the client.
Finally, it adds a missing requirement of oslo.serialization to requirements.txt.
