bgp: show VPNv4 Prefix information

Browse Source 
But the result looks unexpected regarding of show_command .
I can’t find the advertised labels or assigned labels for vpnv4 prefix .
 (reference: http://sourceforge.net/p/ryu/mailman/message/32686423/ )
Therfore, I've patched the codes for formatting as follows .
=> needs for fixing labels attribute after that .

INFO:bgpspeaker.api.base:API method operator.show called with args: {'params': ['rib', 'all'], 'format': 'cli'}
