> - REPL DUMP syntax:
> {code}
> REPL DUMP <repl_policy> [FROM <last_repl_id> WITH <key_values_list>;
> {code}
> - New format for the Replication policy have 3 parts all separated with Dot (.). 
> 1. First part is DB name.
> 2. Second part is included list. Comma separated table names/regex with in square brackets[].
 If square brackets are not there, then it is treated as single table replication which skips
DB level events.
> 3. Third part is excluded list. Comma separated table names/regex with in square brackets[].
> {code}
> <db_name> -- Full DB replication which is currently supported
> <db_name>.['.*?']  -- Full DB replication
> <db_name>.[] -- Replicate just functions and not include any tables.
> <db_name>.['t1', 't2']  -- DB replication with static list of tables t1 and t2
included.
> <db_name>.['t1*', 't2', '*t3'].['t100', '5t3', 't4'] -- DB replication with all
tables having prefix t1, with suffix t3 and include table t2 and exclude t100 which has the
prefix t1, 5t3 which suffix t3 and t4.
> {code}
> - Need to support regular expression of any format. 
> - A table is included in dump only if it matches the regular expressions in included
list and doesn't match the excluded list.
