Goals

1. Be able to passthrough arbitrary args in the same way as passThroughEnv, to prevent them contributing to the cache key.

Background

Currently in our CI, we use sharding to split our E2E tests.

This results in a command something like yarn test:e2e -- -- --project=foo --shard=1/3

This then triggers a cache miss (due to the arbitrary args), causing a full build before e2e is ran.

We are currently getting around this by doing yarn build in a prior step to ensure everything is built, and then passing --only to the test command.

Proposal

It would be ideal if there was a way to omit the passthrough args from a specific task.
This would mean we could still rely on turbo to guarantee the rest of the dependency graph is built.

Potentially part of the turbo.json in the same way as tasks.passThroughEnv.
