Collects various information about the SCSI devices install on the host
system.
This plugin will capture a large amount of data from the /sys filesystem,
as well as several different invocations of the `lsscsi` command.
Additionally, several `sg_persist` commands will be collected for each
SCSI device identified by sos. Note that in most cases these commands are
provided by the `sg3_utils` package which may not be present by default.
