It mostly looks good, but...

I don't like the idea of hard-coding this in the base class.

I think this should be configurable per-repo or at least per repo type.

This patch clears the way for other repo types to have sub-modules, but
will they be the same mapping for a git tree with those as
sub-modules?  Maybe I'm just not following how the system works
properly...

Alternatively...if the above is wrong/not feasible.  In the
sync/__init__.py you have the choices hard-coded there independently of
these definitions above.  I would prefer that one get it's options from
the other. Since syncbase.py is not gauranteed to be loaded, I would
think that the above be declared in the sync module's __init__.py and
imported or passed in here.  Then the:

"choices": ("glsa", "news", "profiles"),

could become:

"choices": list(_SUBMODULE_PATH_MAP)

Then there is only one place to edit as options or code change.
