LU-4647 nodemap: add tests to sanity-sec for nodemap mapping

Added tests to sanity-sec.sh, as outlined in the original nodemap
spec. The tests currently only work with a single OSS node, but this
will be fixed in a future update. These tests test basic permissions
and quota handling of the nodemapper, as well as ACL mapping.
