Yasin, Siraj (SY495P) fffc42ad8a Enable golint as part of golangci-lint.
Issues raised after enabling golint as part of golangci-lint

  * error var ToDiscoveryError should have name of the
	form ErrFoo (golint)
  * error strings should not be capitalized or end with punctuation
	or a newline (golint)

Issues not raised by golint embedded within golangci-lint

  * comment on exported function <funcname> should be
      of the form "<funcname> ..."

So kept the golint standalone tool also in Makefile
