While trying to answer and verify the concerns of this discussion fluxcd/notification-controller#540 (comment) about static/statusless objects and their compatibility with kstatus, and also to make #4298 CLI readiness check of static objects, easier and better, I found that all the readiness checks in CLI can be simplified by using kstatus itself and we no longer need to question if our API works with kstatus or not. With this change, all the readiness checks in the CLI will be performed using kstatus. If any of the Flux API objects break kstatus compatibility, they won't work with the CLI. Making it easier to answer what's kstatus compatible and not.

This change replaces all the many functions and ways of calculating readiness of objects into one unified way that uses kstatus.Compute() to check if the object is in progress or current. Only the objects that are current are considered to be ready. This takes advantage of the kstatus compatibility of Flux's APIs and also makes sure that they remain kstatus compatible.

The new isObjectReady() function is also aware of static/statusless objects and knows how to check their readiness using kstatus. This prepares the CLI for the upcoming static API objects.

All the is*Ready() functions for specific objects have been removed.

This change doesn't affect any of the existing e2e test results.

Introduce suspend and resume subcommands for alert-provider. This was needed to fully implement the reconcilable interface for alert-provider in order to use the new common readiness check.
