Feature Request

Is your feature request related to a problem? Please describe:

Old versions' TiDB has some bugs. Sometimes it's much easier to avoid these problems on dumpling rather than on TiDB.

Describe the feature you'd like:

wrong TiDB information.schema result

BUG: TiDB's information_schema.columns and information_schema.tables will miss some information if we drop <database> and then set a tidb_snapshot to dump dropped data.
Affected version: TiDB v3.0.5

#305 has fixed this PR. Because we use show table status to replace intomation_schema.tables.
