Pipeline often fails with timeouts ~2 hours on the test step.

For comparison a clean local build takes around 35mins and a test ~40mins (requires building and executing tests)

Running the test suite in 1 hour seems like a reasonable target

Some options to improve this:

Upgrade circleci plan with more CPU allocation
Switch CI altogether to get more CPU (parity uses gitlab)
Optimize caching with sccache
Chunk tests by crates. we run them all in one step cargo test --all at the moment
