[E2E/Quickfix] Move E2E pre-run script to protocol-infra

[okdas]

Summary

Fixes some e2e tests issues:

• First e2e test consistently failed, requiring a retry;
• We have a check that waits for all actors to become online before running e2e test. Previously it relied on 200 statuses. Now with REST relay support we also can accept other HTTP status codes.
• Moves the check script to the protocol-infra repo.

The CI will now also run the e2e tests on devnet, which increases the time it takes to complete all CI checks.

You may need to run make trigger_ci to submit an empty commit that'll trigger the tests.

If you also want to run E2E tests, please add devnet-test-e2e label.
