utilities: add conditional {start/stop}_ic_ovsdb on start_ic command

This commit adds capability to start and stop ovsdb-server for OVN interconnection
when {start,stop}_ic is called.
It changes previous behavior where {start,stop}_ic only started/stopped ovn-ic daemon without ovn-ic DBs.

If one wants to save previous behavior, --ovn-manage-ovsdb=no must be passed to ovn-ctl script.
