[DB2] Creating temporary tables

[aguibert]

Over in https://github.com/hibernate/hibernate-reactive/pull/325 they were trying to create temporary tables and this was not working (no stack trace at the moment).

An example of the SQL being used is:

declare global temporary table foo(id int)

@aguibert Alright, so I managed to get it to work using

create global temporary table

instead of:

declare global temporary table

And by running:

create user temporary tablespace hreact1 managed by system using ('hreact')

when the test suite starts.

So this is now no longer a high priority for me.
