HC2VPP-257: MPLS interface management
Translates /hc2vpp-ietf-routing:routing/hc2vpp-ietf-mpls:mpls/interface to sw_interface_set_mpls_enable which is equivalent to: set interface mpls [...] enable MPLS table is created before configuring MPLS using mpls_table_add_del (required since VPP 17.10). Reading MPLS configuration state is not supported (VPP API is missing). Change-Id: I3f1b987c3669b0836a27649a711e75d0dc37a779 Signed-off-by: Marek Gradzki <mgradzki@cisco.com>
