[GH-170] Fix CI Hydra issue

[ksaric]

#170

Fix the failing CI and remove unnecessary Nix derivations.

[ksaric]

It would be nice if somebody reviewed #167 so we can merge that, rebase this and then merge this to fix all CI issues popping up:

• [GH-96] T1.2.1 QuickCheck state machine tests, added IPC. #167
• Fix various CardanoConfiguration types #168
• Update document #148

runCoveralls is not needed anymore? (can be removed from default.nix then?)

[ksaric]

@jbgi Good point, I'll put that back.

[ksaric]

Added ci/hydra:Cardano:cardano-shell:required branch protection. Thanks @jbgi.

[ksaric]

Why isn't Coveralls working? 🤔
Do we need to add it to the CI pipeline? And if so, won't that void the Hydra caches when building it?

Otherwise, I have no clue why it's not working.

[HirotoShioi]

I've managed to run the test locally so if coveralls are fixed, LGTM

[ksaric]

We can leave the coveralls issue for another task, not urgent.

@ksaric Seems that 30829cc#diff-8b496edab86012a437e80897eb7129c0 removed coverage checking.

[ksaric]

@365andreas Yep, I noticed that. Adding it here results in:
