Check Gitaly when running `rake dev:setup`

Before this change, trying to setup dev environment could be tried without having at least one Gitaly running. Cloning the repositories would fail, but not stop the setup. Given this would lead to an inconsistent state, a check was added if we could connect to the server. Output when it fails: ``` $ rake dev:setup Failed to connect to Gitaly... Error: 14:Connect Failed ```
