Driver does not handle custom type columns properly in C* 3.x.

In 3.x, the type attribute in C* column metadata is the name of a CQL datatype (e.g. text, int, etc.) instead of a fully qualified class name (e.g. org.apache.cassandra.db.marshal.Int32Type).

However, custom types are expressed as a fully qualified class name, with single-quotes around them (e.g 'org.apache.foo'). The Ruby driver does not parse this properly and stack traces when starting up.

Unfortunately, there is no workaround.
