Mehdi Abaakouk 09a2f0994f Use werkzeug to run the developement API server
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
