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 Nova API and api-metadata. Therefore, this patch adds two new nova_api_uwsgi_config and nova_api_metadata_uwsgi_config providers as well as two new nova::wsgi::uwsgi_api and nova::wsgi::uwsgi_api_metadata classes.
