fix: add standalone pod tracking support

[drey]

This PR adds standalone pod tracking support. Before this PR this case was covered by generic tracker and standalone pod actual state was not considered during deploy.

The current implementation exposes container logs, tracks readiness, and reflects the actual pod status.

Operation was tested by using the following template:

apiVersion: v1
kind: Pod
metadata:
  name: multiline-sh-pod
spec:
  restartPolicy: Never
  containers:
    - name: main
      image: alpine:latest
      command: ["sh", "-c"]
      args:
        - |
          echo "Echo standalone pod is running.."
          sleep 15
          touch /tmp/ready
          echo "Pod is ready"
          echo "Stopping standalone pod.."
          sleep 5
          echo "Exiting"
          exit 0
      readinessProbe:
        exec:
          command:
            - /bin/sh
            - -c
            - cat /tmp/ready && exit 0 || exit 1
        initialDelaySeconds: 5
        periodSeconds: 10
        timeoutSeconds: 2
        failureThreshold: 3
