ssh: T6192: allow binding to multiple VRF instances

Currently VyOS only supports binding a service to one individual VRF. It might
become handy to have the services (initially it will be VRF, NTP and SNMP) be
bound to multiple VRFs.

Changed VRF from leafNode to multi leafNode with defaultValue: default - which
is the name of the default VRF.
