- Have the get_scsi_ids() utility method return a dict, while adding occupied_ids. Leverage this to improve the logic for detecting which IDs are available to be reserved in the Web UI. (Which fixes a recent regression bug that's causing no IDs to be detected as available to be reserved.)
- Improve /scsi/attach endpoint logic to capture dynamic parameter fields now prefixed with "param_" (previous it scanned for any arbitrary field, which wasn't very accurate or secure)
- Added Product string to the block_size:512 CD-ROM device, so that it's obvious when it's being used.
- Tweaked test data for attach_device tests
* Read the drive properties file once and store it in the Flask app config. Spin out the drive properties formatting to a helper method.
* Add empty removable disk drives to the attach peripherals UI
* Refinement of UI labels and help text, moving some context to the wiki
