Paul Hauner aea43b626b Rename random to prev_randao (#3040)
## Issue Addressed

As discussed on last-night's consensus call, the testnets next week will target the [Kiln Spec v2](https://hackmd.io/@n0ble/kiln-spec).

Presently, we support Kiln V1. V2 is backwards compatible, except for renaming `random` to `prev_randao` in:

- https://github.com/ethereum/execution-apis/pull/180
- https://github.com/ethereum/consensus-specs/pull/2835

With this PR we'll no longer be compatible with the existing Kintsugi and Kiln testnets, however we'll be ready for the testnets next week. I raised this breaking change in the call last night, we are all keen to move forward and break things.

We now target the [`merge-kiln-v2`](https://github.com/MariusVanDerWijden/go-ethereum/tree/merge-kiln-v2) branch for interop with Geth. This required adding the `--http.aauthport` to the tester to avoid a port conflict at startup.

### Changes to exec integration tests

There's some change in the `merge-kiln-v2` version of Geth that means it can't compile on a vanilla Github runner. Bumping the `go` version on the runner solved this issue.

Whilst addressing this, I refactored the `testing/execution_integration` crate to be a *binary* rather than a *library* with tests. This means that we don't need to run the `build.rs` and build Geth whenever someone runs `make lint` or `make test-release`. This is nice for everyday users, but it's also nice for CI so that we can have a specific runner for these tests and we don't need to ensure *all* runners support everything required to build all execution clients.

## More Info

- [x] ~~EF tests are failing since the rename has broken some tests that reference the old field name. I have been told there will be new tests released in the coming days (25/02/22 or 26/02/22).~~

Consensus Specification Tests

This crate parses and executes the test vectors at ethereum/consensus-spec-tests.

Functionality is achieved only via the $ cargo test --features ef_tests command.

Running the Tests

Because the test vectors are very large, we do not download or run them by default. To download them, run (in this directory):

$ make

Note: this may download hundreds of MB of compressed archives from the ethereum/consensus-spec-tests, which may expand into several GB of files.

If successful, you should now have the extracted tests in ./consensus-spec-tests.

Run them with:

$ cargo test --features ef_tests

The tests won't run without the ef_tests feature enabled (this is to ensure that a top-level cargo test --all won't fail on missing files).

Saving Space

When you download the tests, the downloaded archives will be kept in addition to the extracted files. You have several options for saving space:

  1. Delete the archives (make clean-archives), and keep the extracted files. Suitable for everyday use, just don't re-run make or it will redownload the archives.
  2. Delete the extracted files (make clean-test-files), and keep the archives. Suitable for CI, or temporarily saving space. If you re-run make it will extract the archives rather than redownloading them.
  3. Delete everything (make clean). Good for updating to a new version, or if you no longer wish to run the EF tests.
