Add fmt and clippy

[alvicsam]

Can I suggest using gitlab-ci instead of GHA?

What would be the benefit in this case ?

What would be the benefit in this case ?

Almost all our projects use gitlab-ci and in future we want to have unified pipeline for all projects (at least the repeatable steps). So it's better to have one unified instrument for CI.

Found out that paritytech/ci-linux doesn't have not fmt, nor clippy >_<
But I'll fix it.

For now, I am mainly working on fixing the issues related to those checks.

Whether we do the checks in github or gitlab can be discussed. I would prioritize simplicity and speed, this is why I went for GHA since this is supposed to be a quick check and not a big mechanics.

Ultimately, I don't mind but I find GHA more convenient for those, especially because we could have one Github Action that we use adn reused in most repos.

For big and heavy runs, I am with you on the choice of gitlab though.

NOTE: In your pipeline, you should run fmt first as it runs much faster and thus can fail much faster.

fmt took 2 minutes, so it's relatively quick :) And it's just 5 lines in .giltab-ci.yml

Currently they are in one stage, so they run simultaneously.

p.s. still need to add clippy to ci image

&kubernetes-env lacks image: "${CI_IMAGE}" directive.

Already done. Ty anyway.

I know that this runs stuff on gitlab,but I don't see any advantage in this anyway, so I'm going to close this pr.
