Refactor flake, shells and hydraProject

[locallycompact]

We no longer need .#ci. input-output-hk urls are stale. Moves pkgs and tools to the top level and simplified the haskell.nix project function. Removes` impure argument defaults like currentSystem and <nixpkgs>.

Transactions Costs

Sizes and execution budgets for Hydra protocol transactions. Note that unlisted parameters are currently using arbitrary values and results are not fully deterministic and comparable to previous runs.

• The minting policy hash is only usable for comparison. As the script is parameterized, the actual script is unique per Head.

End-To-End Benchmark Results

This page is intended to collect the latest end-to-end benchmarks results produced by Hydra's Continuous Integration system from the latest master code.

Please take those results with a grain of salt as they are currently produced from very limited cloud VMs and not controlled hardware. Instead of focusing on the absolute results, the emphasis should be on relative results, eg. how the timings for a scenario evolve as the code changes.

I like the refactoring, but you are stripping off some (to me) essential comments and I would like to retain them.

Also, the fact that we have the tools defined far away from where we actually need them (only in shell.nix) is making this harder than necessary to read/understand.
