Title: make statsrelay handle missing carbon/statsd stanzas better

Before if you were missing a `carbon` or `statsd` section from the config, statsrelay would complain (although still run). This makes it only complain to stderr when both sections are missing (if one section is missing it will be logged in a less scary way still). This also makes handling empty configs work better, since it will know not to start the event loop now.
