T6867: Add linter and unit test engine for Go(lang)

Summary

Add support for running Unit Test for Go.

This differential adds two new configuration options:

unit.go.godep bool: If enabled and Godeps folder is found at the root of the repository, the tests will run through godep. Default: true
unit.go.race bool: If enabled, race detection will be run. Default: true

Test Plan

Test in https://github.com/julienschmidt/httprouter, must add the following arcconfig file

{
  "phabricator.uri" : "https://secure.phabricator.com/",
  "unit.engine": "GoTestEngine"
}

Then make a breaking change and run 'arc unit'.

Example output:

To test the race detection:

Create arc_test.go

package test

import "testing"

func TestShouldNotPassRaceTest(t *testing.T) {
        var myString string

        go func() {
                myString = "hello"
        }()

        go func() {
                myString = "bye"
        }()
}

Output:

@sectioneight Let's add coverage support once this D gets merged.

nice!

59	this is a little awkward, since in the case of non-godep, the `$cmd` will have a leading space. perhaps: $cmd = ''; if ($this->useGodep()) { $cmd = 'godep '; } $cmd .= 'go test -v';
