When starting Arquillian tests, we eventually end up in this line: https://github.com/wildfly/wildfly-core/blob/main/controller-client/src/main/java/org/jboss/as/controller/client/impl/InputStreamEntry.java#L63

There the whole deployment is copied into a byte array before sending it to the server for deployment.

We do not use a minimal deployment with just the test-relevant classes, but the full EAR just with the tests added in, to have a more production-like environment for the tests.

This means the whole big EAR is read into a byte-array and then regularly busts the max-heap.

It would be nice if this could be done instead in some streamed way instead of reading the full deployment to the heap of the test worker process.
