os_vif: Add support for configuring os_vif_ovs plugin

This change add an os-vif lib that declares two new variables
OS_VIF_OVS_OVSDB_INTERFACE and OS_VIF_OVS_ISOLATE_VIF

The former is introduced to workaround bug #1929446 which cause the nova
and neutron agents to periodically block waiting for ovs to respond.

OS_VIF_OVS_ISOLATE_VIF is added to address bug #1734320 when using
ml2/ovs vif isolation should always be used to prevent cross tenant
traffic during a live migration.  This makes devstack more closely
mirror reality by enabling it when ml2/ovs is used and disabling it
otherwise.
