Remove usage of GerritConfig from GitWebServlet

Instead of injecting GerritConfig into GitWebServlet inject what is
needed to get the SSHD listen address and the canonical git URL, since
this is everything GitWebServlet needs. Removing the injection of
GerritConfig allows us to remove the SSHD listen address and the
canonical git URL from GerritConfig and in a later step to get rid of
GerritConfig.
