[FEAT] Initial Discovery Power-On Hours.

[Dire-Pants]

Describe the solution you'd like
I currently log this manually in a spreadsheet but it would be cool if Scrutiny can log the Power-On hours during initial disk discovery into my array and not just the cumulative power-on time extracted from SMARTd. I buy a lot of used/high-hour surplus drives and I would like to know what hours each disk "started" in my specific server to compare the general length of time they inevitably take to fail. I think this information can be useful on top of the MTBF backblaze info. I think it can help users make more informed purchasing decisions...or at the very least be a fun metric to look at "Oh this drive ended up lasting another X years"
