Remove ovs from ovs bridge config

Mentioning 'ovs' in config file for an ovs bridge
leads to a number of issues. Mainly it makes system delete ovs bridge and
all its ports from ovsdb every time on shutdown, and bring all this back
on reboot. This does not work when ovs bridge has non-ovs ports
which is a common case in many MCP deployments.
So on reboot we lose ports and eventually connectivity.

Interface config files for ovs bridges were added to be able
to assign ip address to a bridge and do ifup with no reboot needed
(https://gerrit.mcp.mirantis.com/#/c/29432/) - this should still
be possible with no 'ovs' in bridge config.

Similar change was done with dpdk ovs bridges
