bitbake: bitbake: move configuration reading code

The configuration reading code should live in the
main bitbake entry point, and the server modules should
be supplied with correct configuration instead of attempting
to parse from configuration files.

This patch moves the endpoint address reading from XMLRPC
to the bitbake main script.
