Title: Some environment changes to speed up deploys

* Instead of using pypi.edx.org why not cache on localhost?
Seems to work well and it does result in a speed improvement
for when we need to download packages. This adds the devpi
role as dependency for edxapp
* For edxapp we md5sum all fo the requirements files and only
run the pip installs, bundle, npm tasks if any one of those
files have changed (it treats them as a group)
* Adds convenience symlinks for pip
