Add approaches to help override configmap with operators

[yuzp1996]

Feature request

I want to configure some configurations that exists in configmap with the operator.

Use case

For example, if I want to adjust log level I have to stop tekton-operator and make change in configmap config-logging. If tekton-operator starts the config-logging will be revert.
