[PATCH 8/9] submodule-config: parse_config

[Stefan Beller <sbeller@google.com>]

This rewrites parse_config to distinguish between configs specific to
one submodule and configs which apply generically to all submodules.
We do not have generic submodule configs yet, but the next patch will
introduce "submodule.jobs".
