Documentation - Add "MySQL Memcached Plugin" to "MariaDB versus MySQL - Compatibility" page

I'd like to request that we add something about the "MySQL Memcached Plugin" to the "MariaDB versus MySQL - Compatibility" page:

https://mariadb.com/kb/en/mariadb/mariadb-vs-mysql-compatibility/

MariaDB does not support Memcached plugin, which is mentioned here:

https://mariadb.com/blog/mysql-56-vs-mariadb-100
https://mariadb.com/blog/mariadb-10-vs-mysql-56-feature-comparison-update

But it is not on a standard manual page, and the "MariaDB versus MySQL - Compatibility" page would make a good place for it.

An additional side note, and perhaps could be included somehow, is that customers are able to retrieve memcached stored data since the data is stored as InnoDB tables. MariaDB will startup, and will log an error message stating it cannot find the libmemcached.so library:

[ERROR] Can't open shared library '/.../mariadb-10.1.14/lib/plugin/libmemcached.so' (errno: 0, cannot open shared object file: No such file or directory)
