Image Generation is 10x slower than present rtstats

A current test of the test rtstats and legacy rtstats.

Server	Time
Legacy	0.4s
Test/New	8.2s

Assuming the test host is as beefy as current production host, this difference is likely all due to python being exec'd for each request and not being run from mod_wsgi.

So I will see how fast I can get a mod_wsgi image generation from python to run.

@oxelson will be efforting Python3 + mod-wsgi setup tomorrow on the Unidata test machine. My local testing shows my mod-wsgi implementation on-par for speed with the current legacy site. We shall see how it goes in real life :)

@oxelson got the test server all shined up and running with my mod-wsgi code. So a current test of the example URL above

Server	Time
Current	0.4s
Test	2.7s

Augh. Will have to boggle this some more. My goal here is at least sub 1 second. I have plenty of database + mod-wsgi + matplotlib code on other servers that runs sub 0.5s, so it is possible!
