Add legacy-config new feature

This feature makes the legacy configuration optional.
It was used by brmsgw and other tooling to provision
via its DMaaP channel.   The capability to configure
via PdpConfiguration object is kept in the core
preserving backwards compatibility, but the DMaaP
provisioning channel(s) are optional.
