Move OpenStack requirements to ovs 2.6.0

[Richard Theis]

Move the OpenStack requirements to ovs 2.6.0 for all python version once requirements are opened for Ocata and ovs 2.6.0 is released.

[Richard Theis (rtheis)]

Open vSwitch 2.6.0 released: http://openvswitch.org/pipermail/discuss/2016-September/022786.html

Once this ovs python package is released on pypi (https://pypi.python.org/pypi/ovs), this issue should be ready to be resolved.

    Workaround OVS transaction mutate bug

    Using OVS transaction mutate support causes the updated column to
    be an empty list after the mutation. This results in subsequent
    actions taken based on the column data to be incorrect. The column
    data is accurate again once the current transaction completes. It
    appears that the OVS python IDL is not properly handling getattr()
    after column mutation.

    This workaround is needed until OVS is fixed. The workaround drops
    transaction mutate support for logical router static routes since
    they require numerous column data comparisions within a single
    transaction. In addition, OVN DB sync ACL processing had to be
    modified to ensure mutations wouldn't impact any comparison. At
    this time, no other problems where identified.

    The functional tests were updated to test the logical router
    static routes problem and other paths with multiple commands
    within a mutate transaction.

    Recent neutron relocations also required a couple minor unit
    test updates.

    Update tox install to support constraints and branches

    Update tox.ini and tox_install.sh to support constraints and branches.
    This also includes an update per [1] since the post queue can constrain
    targets. This will be cherry-picked to stable/newton and modified to
    use the appropriate stable/newton branches.
