Jenkins is a continuous integration environment, widely used in industry

for running automated test suites, performing deployments, as well as

many other use cases.
This change adds a Jenkins integration to Review Board. This will enable

users to add this integration and have new review requests trigger

builds on a Jenkins server.
This additionally features a Jenkins plugin. This plugin features two

build steps. The first build step, to occur prior to the main job's

build steps, applies the review request's diff using rbt patch. The

second, post-build step notifies review board of the build's status.
rbintegrations/util/urlrequest.py featured duplicate code from the

reviewboard repository, reviewboard.hostingsvcs.service.URLRequest.

That class is currently an internal class, so rather than importing it

in all files that use it in this repository, for now we'll import it

once in this file. Once URLRequest is refactored in the reviewboard

repo, we can remove the urlrequest.py file and import the original

class.
