What problem does this PR solve?

Issue Number: close #17463

This PR adds global variable tidb_slow_log_masking to control masking slow log query.

Such as below:

  1. Enable the tidb_slow_log_masking first.
 set @@global.tidb_slow_log_masking=1;
  1. Then, when TiDB record the slow log, it will masking the user data of SQL,
    just like SQL normalize, such as below:
# Time: 2020-06-03T18:28:39.886171+08:00
...
...
...
select count ( ? ) , sum ( query_time ) , digest from information_schema . cluster_slow_query where time >= ? and time < ? group by digest order by sum ( query_time ) desc;

The original SQL is:

select count(*), sum(query_time), digest from information_schema.CLUSTER_SLOW_QUERY where time >= '2020-03-05 20:55:00' and time < '2020-06-05 20:57:00' group by digest order by sum(query_time) desc;
