> Allow to attach the native masking functions added by CASSANDRA-17941 to table columns, as defined by [CEP-20|https://cwiki.apache.org/confluence/display/CASSANDRA/CEP-20%3A+Dynamic+Data+Masking]. 
> {{CREATE TABLE}} statements would look like:
> {code}
> > CREATE TABLE patients (
>       id timeuuid PRIMARY KEY,
>       name text MASKED WITH partial(2, 1),
>       birth date MASKED WITH default()
>       );
> > INSERT INTO patients(id, name, birth) VALUES (now(), 'alice', '1982-12-21);
>  
> > SELECT name, birth FROM patients;
>  
>  name    | birth
> ---------+------------
>  alXXXXe | 1900-01-01
> {code}
> {{ALTER TABLE}} statements would look like:
> {code}
> > ALTER TABLE patients ALTER name MASKED WITH partial(2, 1);
> > ALTER TABLE patients ALTER name WITHOUT MASK;
> {code}
> It won't be possible to use masked columns in the WHERE and IF clauses of SELECT and UPDATE statements.
