Created an initial suite of tests to make sure that the RaSCSI is working properly (#33)

* First cut of very simple robot tests

* Remove log files and change test to use rascsi host name instead of hard-coded IP

* Added more keywords

* Added tests to check the reported SCSI vendor, revision, model and type

* Moved the Linux (host) utilities to a different file

* Added cdrom tests

* Added cdrom tests

* Finished up cd-rom tests. All tests pass, except for Anex86 drive
