Quick and Dirty fix for bridge controller ip address

Quick and Dirty fix for bridge controller ip address
Rather the using the hardcoded value, using the  local host ip address.
This is dirty fix, we should remove it once we get the valid fix using
the connectionInfo local ip address. I think local ip address issues is now
fixed for conncetion-info, so we can probably use that. We need to merge the
 master to netvirtsb branch, that will bring that fix.
With this fix, netvirt create br-int and install all the pipeline flow
successfully.
