As we attempt to get more of OpenStack API servers to be runnable as a regular WSGI application, we should provide support in PBR for building these base scripts just like the console scripts. This adds a new 'wsgi_scripts' group which builds a base script that will run under mod_wsgi as expected. It also has a CLI fallback mode, so that the application can be brought up as a wsgiref simple_server for quick local testing and development. All wsgiref servers default to binding to port 8000, but that can be overridden. To support this, and possible future expansion of the script types, the group list now iterates over a dictionary of group_name => template mappings. This includes basic testing. It also includes tests which would run an actual wsgi environment. These are currently skipped as they can't be reliably run in the gate for timing reasons on stdout processing.

Introduction
PBR is a library that injects some useful and sensible default behaviors into your setuptools run. It started off life as the chunks of code that were copied between all of the OpenStack projects. Around the time that OpenStack hit 18 different projects each with at least 3 active branches, it seemed like a good time to make that code into a proper reusable library.
PBR is only mildly configurable. The basic idea is that there's a decent way to run things and if you do, you should reap the rewards, because then it's simple and repeatable. If you want to do things differently, cool! But you've already got the power of Python at your fingertips, so you don't really need PBR.
PBR builds on top of the work that d2to1 started to provide for declarative configuration. d2to1 is itself an implementation of the ideas behind distutils2. Although distutils2 is now abandoned in favor of work towards PEP 426 and Metadata 2.0, declarative config is still a great idea and specifically important in trying to distribute setup code as a library when that library itself will alter how the setup is processed. As Metadata 2.0 and other modern Python packaging PEPs come out, PBR aims to support them as quickly as possible.
