Add python interface to libsss_nss_idmap
    
    To allow to use libsss_nss_idmap from python applications, e.g. the
    FreeIPA server, the patch adds pythin bindings to libsss_nss_idmap. The
    contributed spec file will place the python bindings in a new package
    called libsss_nss_idmap-python.
    
    Alexander Bokovoy <abokovoy@redhat.com> kindly provided the code to
    check the type of the python objects and loop over the list entries.
