This reverts commit dd4941459c.
The patch for devstack has merged :
I48c86f94098f1501f0e7f90a265dda7e81440eb0
Related-Bug: 1629133
Change-Id: I69907b256af6218c4cfe7aa2b4ba0508991fe4b9

This patch adds a scenario test that creates an l3 VPN and
assigns two neutron networks/subnets to it. Two nova VMs are
spun up on each network. To verify that the VPN is functional,
i.e., forwards traffic between the two subnets, one of the
VM pings the other one.

Closes-Bug: #1637489 

Our tempest test scheduled on osic-cloud1 all get stuck
in requirements installation.
The problem was diagnosed (fungi, tmorin) to be related
to the fact that the neutron devstack code for setting
up routers is installing via br-ex a route to SUBNETPOOL_PREFIX_V4,
which defaults to 10.0.0.0/16, which in the case of
osic-cloud1 contains the gateway IP to reach the Internet
(10.0.0.1):
fungi@ubuntu-xenial-osic-cloud1-s3500-5253075:~$ ip ro sh
default via 10.0.0.1 dev ens3 onlink
10.0.0.0/16 via 172.24.5.11 dev br-ex
10.0.0.0/8 dev ens3 proto kernel scope link src 10.5.131.187
172.24.5.0/24 dev br-ex proto kernel scope link src 172.24.5.1
This change is a temporary fix for networking-bgpvpn that
sets SUBNETPOOL_PREFIX_V4 to a prefix *not* containing 10.0.0.1.

Compiling a fresh upstream OVS is not required anymore now
that our tempest job is configured to use xenial.
(Note that the devstack-gate-bagpipe-rc script is only used by the
Openstack CI gate scripts so removing the OVS compilation trigger
does not impact non-gate use of the devstack plugin)

The current ovs master is broken [1].
This is a temporary fix.
The target fix should be switching our dsvm jobs to use xenial instead
of trusty as a base distro.

Most of the changes in d088925891 should
have been made on the branch after it was created. The update to
requirements was the only one that should have been made in master
before the branch.
The change to .gitreview and tox.ini will be made automatically by the
branch script. The other changes should be done by hand in
stable/newton.

This change updates our tree for Newton:
- tell "git review" to push in the stable/newton branch.
- configure tox to use the stable/newton upper constraints file
- let tox test UTs with newton release of networking-bagpipe
- let devstack jobs to use newton branch of networking-bagpipe

remove override of DEVSTACK_GATE_TEMPEST that is defined in jenkins job,
and run only bgpvpn's tempest tests using a regex filter.

Follow changes made in how Neutron devstack handles
compiling a fresh OVS (see Ia7ad1658b95d7404384c7cae833008a57e3e5af1).
The benefit is that our devstack code is simplified.

Change jenkins job rc file to enable bagpipe-bgp service
and configure it with the OVS MPLS dataplane.
This will automatically enable the bagpipe_bgpvpn OVS agent
extension.
It will also compile and install a recent OVS in the gate
(reusing neutron devstack scripts for this purpose).
Fix xtrace restoration.

Adding rc files to allow to control the gate jobs parameters
without having to touch Jenkins job definitions in project-config.
