Make tracing-web jetty server start faster

[joshelser]

When starting Jetty to run the tracing-web war, it typically takes about 40seconds to actually start. Jstack'ing the process, it spends a bit of time scanning the classpath looking for certain annotations.

Poking around, I think this is actually jersey-moxy (not jersey's jax-rs impl itself) looking for providers. Hopefully there would be a way to turn this off, but I haven't found it yet.
