Feature (helm): add configuration options in values.yaml for all kor arguments

[sleeyax]

Is your feature request related to a problem? Please describe.

Currently, it's possible to customize all kor parameters through the args value in values.yaml. It's great that this option exists, but if you have a lot of parameters to specify this isn't ergonomic:

--set "cronJob.args={pvc\,secret,--delete,--no-interactive,--include-namespaces=$PROJECT_NAME}" \

Also, another minor related issue: when cronJob.namespaced is specified, it overrides all the other args specified.

I think a decision should be made here to either opt for full customization of the parameters through values.yaml (preferred) or deprecate namespaced in favor of args.

Describe the solution you'd like

Add configuration options for each flag to values.yaml.

For example:

cronJob:
  resources: []
  delete: false
  excludeLabels: []
  excludeNamespaces: []
  groupBy: namespace
  ignoreOwnerReferences: false
  includeLabels: ""
  includeNamespaces: []
  kubeconfig: ""
  newerThan: ""
  noInteractive: false
  olderThan: ""
  output: table
  showReason: false
  slack:
    authToken: ""
    channel: ""
    webhookUrl: ""
  verbose: false

Describe alternatives you've considered

Specifying all the args as shown above works for now (as long as cronJob.namespaced is unspecified).
