Ensure we can use a non blocking thread pool for a blocking one with Loom

Project Loom will add in Fibers and continuations. https://issues.redhat.com/browse/ISPN-11510 already adds in creating virtual threads. However we need to ensure that we can configure a system where the blocking and non blocking executors can point to the same thread pool since Loom will handle the continuation as needed.

We will have to test if these keeps performance the same as well, since the blocking call will still stop that processing, it just can run a different operation while the blocking operation completes.
