Libmemcached dependency resolution
The original runtime basebuild specified a version of memcached since depreciated. If you see yum errors about libmemcached whilst updating, you will need the following workaround (on the runtime).
sudo yum erase libmemcached sudo yum install openathensla-runtime sudo yum install openathensla-proxy
Optional: remove SSLv3 support
