[Boomatang]

Issue link

https://issues.redhat.com/browse/MGDAPI-5758

What

Set resources in the subscription so that the resources values are not taken form the CSV's

Verification steps

• install RHOAM 1.36
• check resources on operators in, resources should be set
  • 3scale
  • marin3r
  • observability
• upgrade to this branch
• recheck the resources on the operators
• EXPECTED: resources set to the namespace default which does not include values for the limits.

Tested this on cluster and can see that the resource config is set on the deployment before the change, and it gets removed after:

1.36.0 deployment:

containers:
  - resources:
      limits:
        cpu: 100m
        memory: 300Mi
      requests:
        cpu: 100m
        memory: 300Mi

This PR deployment:

containers:
  - resources: {}

1.36.0 subscription:

spec:
  channel: threescale-mas
  installPlanApproval: Manual
  name: 3scale-operator
  source: rhmi-registry-cs
  sourceNamespace: redhat-rhoam-3scale-operator

This PR subscription:

spec:
  channel: threescale-mas
  config:
    resources: {}
  installPlanApproval: Manual
  name: 3scale-operator
  source: rhmi-registry-cs
  sourceNamespace: redhat-rhoam-3scale-operator

Can see that the limits are removed across the board post upgrade:
