Title: Zend\Db\Metadata: Add allowed values in errata for ENUM and SET column types

Reads ENUM/SET permitted values from MySQL them from the database, parses them into an array and sets it in the column errata data.

PostgreSQL also supports ENUM (and maybe SET), I'd need to install it to test properly. I'll see if I can get it added.
