Prevent spawning two VPN agents
Currently, if the VPN devstack plugin is enabled (which is
the method used for VPN in all test jobs), there will be
two VPN agent processes started. This doesn't seem to
affect the tests, but is incorrect.
To resolve this, the proposal is to do this in two steps.
With this commit, the script is modified to start the q-vpn
process, if q-vpn is enabled (legacy), and to only start
q-l3 process, if neither q-vpn nor neutron-vpnaas is enabled.
Once committed, the opertion will be the same - if no VPN
service is enabled, we get q-l3 (correct); if legacy q-vpn is
enabled (only), we get q-vpn (correct); if the plugin is used
(the default), we get two q-vpn processes started (wrong).
With a separate plugin commit (to be pushed next), the plugin
will be renamed to neutron-vpnaas, and then we'll get only
one agent process (q-vpn or neutron-vpnaas) runing. We can't
commit the plugin first, because both the VPN agent and the
q-l3 agent will be started at once (just as bad, if not worse).
