Implement Observe Func

[fahedouch]

What problem are you facing?

Like other Crossplane providers, Ansible provider should observe External Resource and save its observations in managed.ExternalObservation than send it to the Reconciler.

I think that we can check wether the managed ressource is ResourceUpToDate using ansible-playbook --diff --check

PS : our ansible-playbook sdk github.com/apenella/go-ansible/pkg/playbook natively support diff and check option https://pkg.go.dev/github.com/apenella/go-ansible/pkg/playbook#pkg-constants

How could Crossplane help solve your problem?

@fahedouch FYI: I logged an issue in Ansible community while ago, and they had the same suggestion using diff, ansible/ansible#75248, but that has limitations.

Hey @morningspace ,

Yes I faced this limitation with shell tasks ( --check is not able to detect changes) . I think we should warn users of cases where the check is not effective by ansible-playbook
