SRE Documentation additions for more installation info on MCAD and Instascale

[jbusche]

Created issue in MCAD, but asked to move to Operator Issues - so closing older MCAD issue 537

The idea is to have a resources/.md file with additional information for SREs

Method to swap out the images when needed
How to change the resources
Maybe how to apply via subscriptions if you don't have the OpenShift UI handy
Cleanup steps

This is what I have on my notes to change MCAD and InstaScale resources. (NOTE, this only persists under the FAST channel version of ODH 2.0.0)

Edit the CR for either mcads or instascale like this:

kubectl edit mcads mcad
or
kubectl edit instascales instascale

And then add this under the spec section:

  controllerResources:
    limits:
      cpu: "1"
      memory: 1G
    requests:
      cpu: "1"
      memory: 1G

Method to replace existing MCAD or InstaScale images. (NOTE: Even though this replaces the images, that doesn't mean the newer or older images work or are tested with the installed CodeFlare stack..)

kubectl edit mcads mcad
or
kubectl edit instascales instascale

and under spec: add something like this:

spec:
  controllerImage: quay.io/project-codeflare/mcad-controller:main-v1.30.0

or for InstaScale:

spec:
  controllerImage: quay.io/project-codeflare/instascale-controller:v0.0.4

@jbusche It seems out dated since the CFO redesign. Would you know if there is anything left to be done?
