support mysql replication style black white list used in dm/lightning
solve https://github.com/pingcap/dumpling/issues/2

Support mysql replication style black and white list first, which used by `lightning` and `dm`. And then we consider to introduce a new black and white list similar to `.gitinore` style, which would make dumplings easier to use, so I add a `mode` to select black and white list style

kennytm: Integration test failed.
GregoryIan: @kennytm PTAL
siddontang: IMO, "old tools style" is a bad name if the user doesn't know DM or lightning. 
3pointer: LGTM
