Add GH Actions which will build Dockerfile if updated

[antonbabenko]

GH Actions for pull-requests which runs docker build when Dockerfile changes and run the smoke test?

No need to push it to GHCR but just getting versions should be enough. Similar to this one - https://github.com/antonbabenko/pre-commit-terraform/blob/master/.github/workflows/build-image.yaml

Hey, can I work on this?

[antonbabenko]

Sure, @mohitsaxenaknoldus !

[mohitsaxenaknoldus]

Where can I find the smoke tests?

[MaxymVlasov]

If you write them and populate them somewhere in the tests/ folder + info on how to use them in .github/CONTRIBUTING.md it will be helpful.

For now, we have only some kind of performance tests

[mohitsaxenaknoldus]

So I also have to create the smoke tests as well then?

[MaxymVlasov]

Yep

[mohitsaxenaknoldus]

I've added workflow which will build the Dockerfile if it was changed but I've never worked with smoke tests before :(

[mohitsaxenaknoldus]

Here's the work so far: #318

[MaxymVlasov]

Maybe we already have the simplest optimistic smoke test here:

@antonbabenko do you'd like to have pre-commit run on some predefined code for each hook? Or what do you mean by "smoke test"?
