Title: Cache options

NOTE: This PR is based of https://github.com/zendframework/zf2/pull/940

* AdapterOptions triggers an "option" event each time an option is going to change AND the options instance has been passed to an adapter instance
* update capabilities in base of a changed option like namespace_separator, no_atime, no_ctime
* allow empty namespaces
* simplified memcached options to be more free setting Libmemcached options because of changes within ext/memcached, now such options can be changed after passing it to the adapter instance
