Support DB Schema in Configuration Node

[SebStaeubert]

Currently there is no way to directly set the schema. It would be nice if there were a field in the configuration node to enter the schema. Maybe in the tab "Security" next to "User" / "Password".
Otherwise it could be placed in the tab "Connection" next to "Database" or as parameter as part of the database-string, i.e. "?searchpath=<schema>" or "?currentSchema=<schema>".

This would be very helpful to avoid setting the search_path in every query node like this:

SET search_path TO {{{ msg.db2_schema }}};

"msg.db2_schema" is an environment variable where i define the schema name as a workaround in my case.

That sounds reasonable. Would you feel like trying the send a PR?

Not without help and not in the next few weeks, but i it's not impossible, i think ;-)
