[TEST] Select free port for Minio (#32837)
[TEST] Select free port for Minio (#32837)

Minio does not support dynamic ports. The workaround here is to scan for a free port first. This is
not foolproof, but as we don't expect too many of these builds to run at once on the same machine,
this should do the trick.
