neutron stadium: full stack coverage

[Isaku Yamahata]

enable full stack coverage: requirement as C4

http://docs.openstack.org/developer/neutron/devref/development.environment.html#fullstack-tests

What to do?
- deploy odl (with optional neutron. without keystone)
- deploy ovs with multiple instance with netns to emulate multi compute nodes
- emulate VM with netns
- send requests to ODL neutron northbound
- test VM/network connectivity by sending packets from netns"

[Rui Zang (rui-zang)]

https://review.openstack.org/#/c/394820/ introduced the first bunch of fullstack test cases to networking-odl, and has been merged.

I am working on devstack + gate job changes.

    fullstack test for networking-odl

    Currently fullstack test cases assume OpenDaylight available at
    http://127.0.0.1:8087/controller/nb/v2/neutron
    test_port_plugging test case creates a port on a network,
    binds port to the current host and verifies port-binding,
    simulates VM vif plugging and verifies flow table entry created.

    Scripts to enable fullstack testing in gate

    1) Introduced an environment variable UNSTACK_KEEP_ODL
       (default False). Once setting to True, do not remove
       ODL while unstacking.
    2) gate_hook.sh -- script to hijack gate job from running
       actual tests.
    3) post_test_hook.sh -- actual fullstack testing is invoked here.

This is the final patch to complete this bug.

[Manjeet Singh Bhatia (manjeet-s-bhatia)]

@Isaku this should be marked complete as net-odl survived the stadium in ocata

[Isaku Yamahata (yamahata)]

fullstack is integrated in Ocata cycle.
Now it doesn't pass, but it's another issue.
