Log:
feature_config: insure featuregroups and applicationmaps are initialized

If the features.conf is missing, the cfg->featurgroups
and cfg->applicationmaps is not initialized, resulting
in assert on ao2_find of a null container.  This patch
changes the initialization call and adds asserts for a
safeguard.
