Add support for gnocchi_api_uwsgi_config in Debian

This patch is adding the configuration of the number of workers,
threads, and the size of the listen queue in Debian, which uses
uwsgi to run Gnocchi API. Therefore, this patch adds a new
gnocchi_api_uwsgi_config providers as well as a new
gnocchi::wsgi::uwsgi_api class.

A new class gnocchi::wsgi::uwsgi exist to allow configuring uwsgi in
operating systems that support this (ie: currently Debian). This helps
configuring the number of processes, threads and listen socket.
Also, a new gnocchi_api_wsgi_config provider now exist.
