So, streaming does not depend on Jetty, but it does use servlet APIs. Since
Spark doesn't pull in any servlet API dependency directly, and instead uses the
transitive one provided by Jetty, which is some Jetty repackaging of servlet
APIs instead of some common dependency. (BTW it works without the explicit
dependency because now it was coming as a transitive dependency of spark-core.)
In light of that I'll restore this dependency, even though I don't really
like it very much (it's pulling a dependency that is too coarse for what it
needs).
