Julia Kreger b8ed6035d5 Change centos DIB_RELEASE default to 9-stream 
Since the public mirrors for centos8 are really not available
anymore since it has gone End of Life, changes the default
invocation for a quick disk image to 9-stream.

Users who wish specific behavior should explicitly express
the version they desire.
