    ovn: Use newer OVS
    
    OVS tag v2.13.0 is not compatible with current used kernel on upstream
    Bionic Ubuntu kernel 4.15.0. This patch sticks to commit hash to unblock
    the gate. We can either change to newer 2.13 tag once released or better
    stop compiling OVS and use one packaged by Ubuntu.
    
    Run functional/fullstack tests with selected OVN and OVS versions
    
    Previously for functional tests OVS version was hardcoded - v2.12.0,
    and OVN was installed from OVS repository.
    
    After we merged OVN driver to Neutron tree we run both
    Neutron/OVS and Neutron/OVN functional tests in one job.
    
    This patch adds possibility to specify from which tag/branch OVS and OVN
    should be checkout.
