BGP: Remove the requirement to rebind a peer to its peer-group under the address-family.
Signed-off-by: Daniel Walton <dwalton@cumulusnetworks.com> Reviewed-by: Donald Sharp <sharpd@cumulusnetworks.com> Reviewed-by: Vivek Venkatraman <vivek@cumulusnetworks.com> Ticket: CM-3868 NOTE: Many of the ibgp peers are not up in the 'show ip bgp summ' output below. This is because ospf was disabled at the time. The main thing to look for is whether or not all of the correct peers are listed based on their 'activate' status.
