Purpose
Linked issue: close #1238
Users can synchronize one or multiple MySQL database into one or multiple Paimon database, It is default false, in this case, all the MySQL database will be synchronized to one paimon database, and the table with same name in different database will be merged, it is suitable for database sharding scenarios. if it is true, the parameter "--database" will be ignored, all the MySQL database will be synchronize to multiple paimon database with the same schema as MySQL before, it is suitable for scenarios with a large number of databases under a database instance, which can save resources.
for new added table in the sync database runtime , I need to get the
databaseNameandtableName,otherwise the test case will be failed, but thedruidframework can not get thedatabaseName, so I merge PR #1621 to this PR, so we should review PR #1621 first , when it is merged to master , I will rebase from the master .Tests
