MPLS: Handle compatibility with old configs

Browse Source 
Old configs do not define MPLS domains and may use a static protocol
to define static MPLS routes.

When MPLS channel is the only channel of static protocol, handle it
as a main channel. Also, define implicit MPLS domain if needed and
none is defined.
