wsgi.simple_server in a mono threaded process that can handle only 5 requests at a time. Even the doc recommands to setup Ceilometer through an other WSGI services like Apache 'mod_wsgi', we can provide a better testing API server. So this patch changes the default HTTP server to the werkzeug one with a autodiscovery of number of workers that we can use. The client queue of werkzeug is 128, so on a 4 cpus machine, ceilometer-api can now handle 512 connections instead of 5. Also the change adds references of how to deploy pecan application in the documentation. The config option enable_reverse_dns_lookup can be safely removed, because werkzeug doesn't do any reverse dns lookup. DocImpact: configuration options changed: enable_reverse_dns_lookup removed, api_workers added Change-Id: If7450b393ea88bc185e5c82b706ace9c38ce350e
