Add support for aodh_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 Aodh API. Therefore, this patch adds a new aodh_api_uwsgi_config provider as well as a new aodh::wsgi::uwsgi class. Change-Id: Ib00be314fe5abc262d4c35f5fbc5612fcd18972d

A new class aodh::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 aodh_api_wsgi_config provider now exist.
