- Tests were not finding the worker binaries
- Workers were not being rebuilt when the version changed
- Made some errors easier to read
* Make a bunch of fixes
* Rebuild nodes on version change
* Fix more issues
* Fix tests
* Pass node version from node into dependencies to avoid recompiles
- [X] get version in CLI
- [X] pass it in to service
- [X] pass version along to PVF
- [X] remove rerun from service
- [X] add rerun to CLI
- [X] don’t rerun pvf/worker’s (these should be built by nodes which have rerun enabled)
* Some more improvements for smoother tests
- [X] Fix tests
- [X] Make puppet workers pass None for version and remove rerun
- [X] Make test collators self-contained
* Add back rerun to PVF workers
* Move worker binaries into files in cli crate
As a final optimization I've separated out each worker binary from its own crate
into the CLI crate. Before, the worker bin shared a crate with the worker lib,
so when the binaries got recompiled so did the libs and everything transitively
depending on the libs. This commit fixes this regression that was causing
recompiles after every commit.
* Fix bug (was passing worker version for node version)
* Move workers out of cli into root src/bin/ dir

There are situations where pruning of the data could take more than a few

move the prune process on a separate thread.

* PVF: Remove `rayon` and some uses of `tokio`
1. We were using `rayon` to spawn a superfluous thread to do execution, so it was removed.
2. We were using `rayon` to set a threadpool-specific thread stack size, and AFAIK we couldn't do that with `tokio` (it's possible [per-runtime](https://docs.rs/tokio/latest/tokio/runtime/struct.Builder.html#method.thread_stack_size) but not per-thread). Since we want to remove `tokio` from the workers [anyway](https://github.com/paritytech/polkadot/issues/7117), I changed it to spawn threads with the `std::thread` API instead of `tokio`.[^1]
[^1]: NOTE: This PR does not totally remove the `tokio` dependency just yet.
3. Since `std::thread` API is not async, we could no longer `select!` on the threads as futures, so the `select!` was changed to a naive loop.
4. The order of thread selection was flipped to make (3) sound (see note in code).
I left some TODO's related to panics which I'm going to address soon as part of https://github.com/paritytech/polkadot/issues/7045.
* PVF: Vote invalid on panics in execution thread (after a retry)
Also make sure we kill the worker process on panic errors and internal errors to
potentially clear any error states independent of the candidate.

* Address comments + couple other changes (see message)
- Measure the CPU time in the prepare thread, so the observed time is not
affected by any delays in joining on the thread.
- Measure the full CPU time in the execute thread.
* Implement proper thread synchronization
Use condvars i.e. `Arc::new((Mutex::new(true), Condvar::new()))` as per the std
docs.
Considered also using a condvar to signal the CPU thread to end, in place of an
mpsc channel. This was not done because `Condvar::wait_timeout_while` is
documented as being imprecise, and `mpsc::Receiver::recv_timeout` is not
documented as such. Also, we would need a separate condvar, to avoid this case:
the worker thread finishes its job, notifies the condvar, the CPU thread returns
first, and we join on it and not the worker thread. So it was simpler to leave
this part as is.
* Catch panics in threads so we always notify condvar
* Use `WaitOutcome` enum instead of bool condition variable
* Fix retry timeouts to depend on exec timeout kind
* Address review comments
* Make the API for condvars in workers nicer
* Add a doc

* PVF: Don't dispute on missing artifact
A dispute should never be raised if the local cache doesn't provide a certain
artifact. You can not dispute based on this reason, as it is a local hardware
issue and not related to the candidate to check.
Design:
Currently we assume that if we prepared an artifact, it remains there on-disk
until we prune it, i.e. we never check again if it's still there.
We can change it so that instead of artifact-not-found triggering a dispute, we
retry once (like we do for AmbiguousWorkerDeath, except we don't dispute if it
still doesn't work). And when enqueuing an execute job, we check for the
artifact on-disk, and start preparation if not found.
Changes:
- [x] Integration test (should fail without the following changes)
- [x] Check if artifact exists when executing, prepare if not
- [x] Return an internal error when file is missing
- [x] Retry once on internal errors
- [x] Document design (update impl guide)
* Add some context to wasm error message (it is quite long)
* Fix impl guide
* Add check for missing/inaccessible file
* Add comment referencing Substrate issue
* Add test for retrying internal errors
