Review Comment:
> Worse yet the use of JettySolrRunner for our tests means that we don't
have any tests for what start.jar is doing.
BATS integration tests is our answer to that. JettySolrRunner just needs to
handle the sequencing realistically (what starts and stops when). You might
have also noticed some bolted-on requirements for tests like debug filter,
proxy port, and more, so I don't see JettySolrRunner going away. It could be
simplified further!
I'm not optimistic about that QuickStart thing helping us -- we've already
tuned Jetty. Most notably, our web.xml has `metadata-complete="true"` thus
there is no annotation scanning.
