> A complete hive warehouse might be required to replicate to a DR site for 
> certain use cases and rather than allowing only a database name in the REPL 
> DUMP commands, we should allow dumping of all databases using the "*" option 
> as in 
> _REPL DUMP *_ 
> On the repl  load side there will not be an option to specify the database 
> name when loading from a location used to dump multiple databases, hence only 
> _REPL LOAD FROM [location]_ would be supported when dumping via _REPL DUMP *_
> Additionally, incremental dumps will go through all events across databases 
> in a warehouse and hence CREATE / DROP Database events have to be serialized 
> correctly to allow repl load to create them correctly.
