* rfc: initial inventory tracking
This just describes the design, not the design alternatives.
* rfc: finish inventory tracking rfc
Also assign it #3. The async script verification RFC should have had a number
assigned before merging but it didn't. I don't want to fix that in this PR
because I don't want those changes to block on each other. The fix is to (1)
document the RFC flow better and (2) add issue templates for RFCs.
* rfc: touch up inventory tracking rfc
* rfc: prune inventory entries generationally.
Based on a suggestion by @yaahc.
* Update book/src/dev/rfcs/0003-inventory-tracking.md
