Prefect 3.0

I use Prefect 2.0 extensively, but it was a pretty big shift from 1.0 and that led to a lot of frustration when trying to debug issues. Wondering how much of a breaking change 3.0 is.

If anyone from Prefect is reading: I would totally pay for your Prefect Cloud if seats came with a reasonable introductory price. Going from zero to thousands per month is just nuts.
