Ansible-based operators: add resource limits

Add into the config/manager/manager.yaml the following limits which are now scaffolded by default:

 ...  # TODO(user): Configure the resources accordingly based on the project requirements. # More info: https://kubernetes.io/docs/concepts/configuration/manage-resources-containers/ resources:  limits:  cpu: 500m  memory: 768Mi  requests:  cpu: 10m  memory: 256Mi 

IMPORTANT: Having resource limits is a best-practice and these values are reasonable defaults, but Operator authors should optimize these values based on their project’s requirements.

See #5274 for more details.

Bump operator_sdk.util in requirements.yml

Update requirements.yml to point to 0.3.1 of operator_sdk.util instead of 0.2.0

See #5462 for more details.

Add annotation to specify the default container

Add the following annotation into the file config/manager/manager.yaml

... template:  metadata:  annotations:  kubectl.kubernetes.io/default-container: manager ... 

See #5330 for more details.

Add PHONY targets to Makefile

Add PHONY target to all Makefile targets. For example, refer to the Makefile in operator-sdk/testdata directory of OperatorSDK tagged by the release containing this change.

See #5330 for more details.

For Golang-based projects, add the flag ignore-not-found into the Makefile for the uninstall and undeploy targets

Update the Makefile with the following changes.

1. Above ##@ Deployment add the following:

... ifndef ignore-not-found ignore-not-found = false endif ... 

2. Replace: sh kubectl delete -f - With: sh kubectl delete --ignore-not-found=$(ignore-not-found) -f -

NOTE You can also compare your Makefile with the one tagged by this release, in operator-sdk/testdata of the OperatorSDK project.

See #5330 for more details.
