HONEYCOMB-355: move BGP to separate distribution
Given current YangBindingProviderModule implementation (HONEYCOMB-358),
needed to preserve footprint of minimal distro.
The change also:
- reverts logger&persistence config changes
introduced by https://gerrit.fd.io/r/#/c/5972/
- improves logging for BGP component initialization
