This patch tries to document and test the following invariant that
should apply for all groups in the environment:
A group should have either child groups, or hosts, not both.
Tests are introduced to confirm and enforce this behavior, based on the
reported failing configuration.
A new function, _check_group_branches, is added which will detect a
failing scenario before code that uses it is executed. If a conflict is
found, a GroupConflict exception will be raised indicating why.
The _check_group_branches function was placed before the physical skel
loading because the problem occurs during that phase; placing this in
the _check_config_settings function would be checking after the error's
already been raised.
A note was also added to _parse_belongs_to to communicate it's implicit
dependence on state as checked by _check_group_branches.
