[Spike] Analyze what can be done with the OpenShift 4.8 to reduce resources

[guillaumerose]

The goal is to run 4.8 and analyze what runs, how many CPU and memory are used.
The second goal is to look at the release notes and check if there is something we can turn on or off.

We already run basic tests, as this is what @praveenkumar relates to with the MCO being an issue.
However, we need a comparison between 4.7 and 4.8 to determine what the memory used is.

The second goal is to look at the release notes and check if there is something we can turn on or off.

This needs some form of conformance tests and resource monitoring. Hopefully @jsliacan or @praveenkumar can chime in to speed up this process.

Reported the previous issue #1287 which demos an application that used to work with about 3-6GB of memory on Minishift/OpenShift 3.x. Still looking for something that can run with less than 16-24GB RAM. Was moved forward into #557, but that also got closed out so pushing this into the pile here as it's been referenced. Happy to show a dev project spinning up using our MW products and operators or templates.

Well, that's not the outcome we were hoping for...
