Remove unused BGP configuration

Configurations under the "bgp" directory implemented the first approach to
test BGP on Podified setups, with all OCP nodes running on a single rack
and EDPM nodes running on separate racks.
This configuration was replaced by bgp_dt01, which deploys OCP nodes and
EDPM nodes splitted in 3 racks. The content of "bgp" became obsole and
it is removed with this patch.
