refactor(deps): migrating from Dep to Go Module

[rodrigo-brito]

• Migrated from Go Dep (Deprecated) to Go Module
• Minor fixes in the code (errchecks, wrong int conversions and unnecessary code)

Thanks @rodrigo-brito!

Could you add these dependencies to go.mod?

go get github.com/sirupsen/logrus@v1.4.1
go get golang.org/x/crypto/acme/autocert@v0.0.0-20191011191535-87dc89f01550
go get github.com/spf13/afero@v1.2.2
go get golang.org/x/oauth2/internal@v0.0.0-20190402181905-9f3314589c9a

We had to install them in order to run make test

Hi @joserenatosilva! Thank you for the review!

• Logrus and Afero packages are already on go.mod (Lines 20, 59)
• go get for acme/autocert and oauth2/internal has no effect here (I think it is not a dependency)
  make test works fine here. Are you testing with go1.17?

I tested with a clean Docker image: docker run -ti --rm -v pwd:/app -w /app golang:1.17 make test and also works

It works as intended, must have been something on my local environment. 😓
