Group configs and factor out config lookup

This CL factors out common code for grabbing the primary and requested configs to be passed along through other handshake steps.  In addition to reducing code duplication and boilerplate, this will be used as a natural way to add a new fallback config (for when Leto is not working) without complexifying the code.
