Subject: [PATCH] Gather uptime and device facts from Solarish systems (#18733)

* Gather device information on Solarish systems

* Gather uptime information on Solarish systems

* Fix typo in variable name

* Add comments and example output from kstat command
Use frozenset instead of set
Make parsing of line a little bit safer
