Add functional test jobs for the v2 client

This adds test jobs for the v2 client, in python2 and python3.

Work items:

* Remove the "functional" tox environment and introduce the "functional-v1"
  and "functional-v2" environments.

* Add zuul base jobs for python2 and python 3 testing. Two jobs inherit from
  each of these new jobs: one for the v1 client and one for the v2 client.

* Add "OS_ENDPOINT" to the list of environment variables forwarded to the
  functional test environments in order to ease local testing.
