yaml based assertion

As a developer I want to use better assertion logic than the following:

- name: Fetch OpenEBS control plane pods ready status
  shell: kubectl get pods -n openebs | grep {{ item }} | awk '{print $2}' | awk -F'/' '{print $1}' && kubectl get pods -n openebs | grep {{ item }} | awk '{print $2}' | awk -F'/' '{print $2}'
  register: ready_status
  with_items:
    - '{{ openebs_components }}'
  until: '{{ ready_status.stdout_lines | unique | length == 1 }}'
  retries: 20
  delay: 5

It will be great to assert list of values in a declarative manner.

For example below yaml should be enough to assert any Pods with the given label to be in Running state. It should return error if there are any Pods that are not Running.

kind: Pod
metadata:
  labels:
    name: app
status:
  phase: Running
