unused attributes
upstart support has been removed in this version
Move uwsgi_runit to uwsgi. Simpler uwsgi recipe.

`graphite_web_config` resource still needs to be used to write the
config first.

uwsgi is now the default and only cookbook supported way to run graphite
web. As such all the extra logic can be removed and just start the service.
