Well, one workaround to consider: We currently decide whether or not to launch RSS by the presence / absence of a "config-rss.toml" file. For now, that has been a sufficient signal - launching RSS has been the only action we'd conditionally take - but it would still be worth making this explicit.

… decision (#1918)

- Adds `hardware` module to Sled Agent for minimally monitoring `devinfo` output. This will certainly evolve, but this PR includes a "bare minimum" real example of tracking the tofino driver.
- Stop relying on `rss-config.toml` to decide if we're running on a scrimlet. Instead...
  - (General case) Rely on monitoring hardware
  - (Testing, manual case) Provide a `force-scrimlet` option to make the sled agent assume that it is a scrimlet

fix it.
