Deletion of SCSI Test Unit Ready Command

Comment: Yeah, this is better served in some other sister project, and I guess someone could transwiki it.  The intention was good, but it's not encyclopedic.  I don't mind out-of-date and useless pages (which can be fixed and updated), but this is basically protocol cruft.  A brief overview of SCSI protocols (such as history, major hurdles, and an example or two) would be fine, but documenting it in detail is not.   seems to cover this fairly well
