Opt-In feature to allow users to publish anonymized smart metric data (and device status -- failed/replaced/working) to Scrutiny for aggregation

this is one of the reasons why I want to eventually integrate (anonymized & opt-in) user provided SMART data. Backblaze's SMART statistics are all based on their datacenter usage, which causes some attributes to be heavily weighted against normal home-server/lab values.
