Extend the cql3 truncate statement to accept attributes, similar to modification statements. To achieve that we define cql3::statements::raw::truncate_statement derived from raw::cf_statement, and implement its pure virtual prepare() method to make a prepared truncate_statement. The latter, statements::truncate_statement, is no longer derived from raw::cf_statement, and just stores a schema_ptr to get to the keyspace and column_family names. `test_truncate_using_timeout` cql-pytest was added to test the new USING TIMEOUT feature.
