Provide more informations in deploy progress log

[StarpTech]

As discussed in slack.

In comparison to skaffold (another deployment tool), kapp only reports if the condition was met or not. I'd like to see more information about the stabilization process e.g:

Waiting for deployments to stabilize...
 - production:deployment/demo: creating container service
    - production:pod/demo-5cf5f768d4-x9xfr: creating container service
 - production:deployment/demo: Readiness probe failed: Get http://10.2.0.161:5002/health: dial tcp 10.2.0.161:5002: connect: connection refused
    - production:pod/demo-5cf5f768d4-x9xfr: Readiness probe failed: Get http://10.2.0.161:5002/health: dial tcp 10.2.0.161:5002: connect: connection refused
 - production:deployment/demo is ready.

check what current error message look like for:

• [ ] probes (readiness liveliness startup)
• [ ] image pull errors
• [ ] container failing at startup (eg wrong command/args)
• [ ] what else (https://kubernetes.io/docs/concepts/workloads/pods/pod-lifecycle/)?
