* Refactoring on atomic rule:
-Main modification: move func gofmt to utils.go
* Refactoring on constant-logical-expr rule

This PR introduces a white & black lists of initialisms for the
`var-naming` rule.
Now the rule can be configured with:
```toml
[rule.var-naming]
arguments = [["ID"], ["VM", "BAR"]]
```
This way, the linter will ignore `customId` but will throw on `customVm` or `customBar`.
