[botanist] Reland "[botanist] Refactor"

This is a reland of 163d0616b0422c582e8cd1c821a1c9e1f43ccb50

Original change's description:
> [botanist] Refactor
>
> Botanist has grown unwielidy over the past ~year and so this change
> returns it to a more manageable and scalable state. Much of the weight
> loss is due to the removal of log support in the multi-device case, which -
> interestingly - has not been used at all or relied upon since its introduction!
> (Indeed, we are creating files (with %d suffixes that we have up front
> not registered as task outputs, and so they never get shipped back to
> the recipe).)
>
> Also removed was botanist's care for not having streamed empty log
> content. This seems like something that should more reasonably be
> checked in the context of a recipe rather than something botanist should
> intimately care about.
>
> Tested: botanist is extensively integration tested being the tool that
> CQ itself consumes from source to run tests and manage device
> interaction. Also, this change can be viewed as bootstrapping
> testability for a more streamlined botanist codebase.
