Replaces rest-client with its stdlib net/http equivalent. Since we're only making HEAD requests, there's little need to haul in rest-client. The fewer dependencies the better.
Note that this tightens up the HTTP check to require a 2xx response. Previously a 3xx response would be followed by rest-client – there's no support for following redirects here.
