Adding git actions

[ranakan19]

added GitActions to do the following:

• get dependencies
• check build
• run tests
• check format
• check go mod status

Fixes #11, #17

parser (binary file) got committed. Perhaps, we can create GiHub Actions to check for binary files.

Seems parser binary should be added to gitignore and removed from that PR

[sleshchenko]

Tested in #21
And seems works as expected:

• tests are disabled - job is finished /~https://github.com/devfile/parser/pull/21/checks?check_run_id=905590865
• tests failed - job failed /~https://github.com/devfile/parser/actions/runs/180806428
• go mod need to be updated /~https://github.com/devfile/parser/runs/905595388?check_suite_focus=true

[sleshchenko]

It's not obvious but as far as I see now - it's better to check go.sum first and them go fmt because go fmt could also add missing dependencies to go.sum. See /~https://github.com/devfile/parser/runs/905595388?check_suite_focus=true

+1 I ran into that as well.

Add "parser" to .gitingore should be good enough. #22

[sleshchenko]

Add "parser" to .gitingore should be good enough.

The question: how that binary was built? If it's needed to manually type a command and specify binary name - anyone is free to name binary as they wish.
If we want to name binary named like parser, or devfile-parser (may be precise a bit) then we can set up Makefile rule to compile with binary with a standardized name which is in gitignore. But it's a bit out of the scope of the current PR.

[sleshchenko]

Approving it not to block PR merging but please address the following issues before merging:

• binary
• go dep
• go.sum and format checks orders

go build will do it. It looks like the default name is picked up from the go module name.
