Add Horizontal Pod Autoscaling

[curtismchale]

Source CM

Pertinent to https://github.com/proudcity/pc-dev-issues/issues/9 we need to add horizontal pod autoscaling to sites. This will track CPU usage and if we hit 80% it will add more pods. Minimum 2 max 4 is likely a good place to start. First we'll need to make sure that the CPU scale is set so that the site can run at 2 pods most of the time as some sites have never had this metric changed.
