feat: get required fields from a resource

[AmitKumarDas]

ProblemStatement: As a SRE admin, I want to fetch required fields from a particular resource. For example, I want to fetch spec.replicas from the Deployment abc running in def namespace.

Draft design

kind: Recipe
spec:
  tasks:
  - name: get-replicas-from-deployment
    get:
      state:
        kind: Deployment
        metadata:
          name: abc
          namespace: def
        spec: 
          replicas: ?

• Above when applied will result in below

kind: Recipe
spec:
  # removed for brevity
status:
  tasks:
    get-replicas-from-deployment:
      object:
        kind: Deployment
        metadata:
          name: abc
          namespace: def
        spec: 
          replicas: 2
