mystreamer不支持在downstream侧重命名database

这是一个需求，比如我用来做历史数据归档时，可能有相同的库名，希望能够通过定义不同的库名对上游加以区分

The master branch have add -2db flag for you.
Usage:

./bin/mystreamer -h 192.168.0.2 -P 3306 -u mock -p mock -db sbtest -2h 192.168.0.3 -2P 3306 -2u mock -2p mock -2db tpsbtest
  -2db string
    	Downstream database, default(if NULL) is same as upstream db

已测，功能ok，但是需要提前建好2db指定的database，是否可以再优化一下，自动创建？
