Subject: bgp: T3759: "l2vpn evpn" and ipv4/ipv6 safi route-targets differ

The "l2vpn evpn" address-family route-target command only accepts a single
route-target value consisting of (A.B.C.D:MN|EF:OPQR|GHJK:MN). The
"ipv4-unicast or ipv6-unicast" address-family route-target command for VPNs
support multiple, whitespace separated route-target values.

This commit adds a new custom validator named "bgp-route-target" with a --single
and a --multi option to pass one or more route-target values.
