Standard Application health status

[arucard21]

Is your feature request related to a problem?

Argo CD does not provide the health status for Application CRDs by default. For an app-of-apps, this causes a problem with sync waves. Applications in the next wave will be immediately installed/updated after the previous wave, without waiting for ones in a previous wave to be fully installed/updated (i.e. become healthy).

Describe the solution you'd like

Argo provides instructions on how to make the application health status available which consists of adding a ConfigMap. It would be convenient if the Helm chart includes this ConfigMap in a way that it can be enabled by setting a value like applicationHealthStatus.enabled to true.

Describe alternatives you've considered

You can still include the ConfigMap for the application health status in your own values.yaml file, as described in the instructions.

Additional context

I think it would be useful to have this health check defined in a more central location. Should it ever need to change, it would only need to be updated in the chart and not in the custom Helm values of everyone using the chart. Other than that, it just seems convenient.
