Update git submodules

* Update docs/submodules/sdnvpn from branch 'master'
  - Merge "Fix testcase3 (peering subcase) for Apex"
  - Fix testcase3 (peering subcase) for Apex
    
     - Fix runnning bgp related commands on Karaf:
       update util.run_odl_cmd() in order to be able to
       run commands on karaf client. Otherwise karaf
       commands fail
     - Ensure zrpcd/bgpd to run on controller side properly:
       Add missing quagga run folder, change owner and
       add user quagga into quaggavt group, in case of apex
       installer
     - Update the way of handling br-ex information and
       parsing out the controller external ip and mask:
       In case we have multiple ip/netmask assigned on br-ex
       the separation was faulty and an extra line, containing
       the second ip address, was added into ext_net_mask variable
