   ## Proposed changes
   
   Support to use current_date() when create async materialized view by adding
   `'enable_date_nondeterministic_function' = 'true'` in properties when create 
materialized view.  `enable_date_nondeterministic_function` is default false.
   
   Here is a example, it will success
   `
           CREATE MATERIALIZED VIEW mv_name
           BUILD DEFERRED REFRESH AUTO ON MANUAL
           DISTRIBUTED BY RANDOM BUCKETS 2
           PROPERTIES (
           'replication_num' = '1',
           'enable_date_nondeterministic_function' = 'true'
           )
           AS
           SELECT *, unix_timestamp(k3, '%Y-%m-%d %H:%i-%s') from ${tableName} 
where current_date() > k3;
   `
   Note:
   `unix_timestamp` is nondeterministic when has no params. it is deterministic 
when has params which means format column k3 date
   
   another example, it will fail
   `
           CREATE MATERIALIZED VIEW mv_name
           BUILD DEFERRED REFRESH AUTO ON MANUAL
           DISTRIBUTED BY RANDOM BUCKETS 2
           PROPERTIES (
           'replication_num' = '1',
           'enable_date_nondeterministic_function' = 'true'
           )
           AS
           SELECT *, unix_timestamp() from ${tableName} where current_date() > 
k3;
   `
   because `unix_timestamp()` is nondeterministic
