HONEYCOMB-374: move BGP to minimal-distribution
Separate BGP distribution was temporary workaround for HONEYCOMB-358 and (partially) HONEYCOMB-360. BGP northbound interface is disabled by default. Change-Id: I72a0f83f40ea96bee478be7d6560f2112611d80f Signed-off-by: Marek Gradzki <mgradzki@cisco.com>
