Add a new type of relation with operator LIKE. Handle it in relation::to_restriction by introducing a new virtual method for it. The temporary implementation of this method returns null; that will be replaced in a subsequent patch. Add abstract_type::is_string() to recognize string columns and disallow LIKE operator on non-string columns. Signed-off-by: Dejan Mircevski <dejan@scylladb.com>
