Title: cassandra_datum/base would attempt to encode all attributes

as strings using "#{value}" which incorrectly serializes hashes
to '{'key' => 'value'} when is then attempted to be parsed as json
when the attribute is read.

this commit fixes that by converting hashes and arrays using the to_json
method.
