This PR refactors notification-controller to implement the new unified standards of Flux controllers (closes: #376) and documents the API usage in the new format (closes: #378, fixes: #433).

The API version v1beta2 is backwards compatible with v1beta1. The only changes are to the .status sub-resource and .status.conditions, which the controller will upgrade on its own. No user intervention is required besides bumping the version in the custom resource definitions.

API changes:

  • Deprecate Receiver.status.url in favor of .status.webhookPath
  • Replace the Stalled=True condition with Reconciling=True and Reason=ProgressingWithRetry on retryable failures
  • Add lastHandledReconcileAt to .status
  • Add spec.interval to periodically reconcile Providers and Receivers with their Secret references to surface config errors after initialisation.
  • The different status phases are now unit tested to ensure that the controller reflects the observed state correctly
  • Enforce a max length of 2048 for URL type fields such as address and proxy
  • Enforce a max length of 255 for the summary field (required by Slack and others)

Controller changes:

Bug fixes included in this PR:

  • Suspended resources where never finalised
  • Receivers were reconciled on .status updates instead of just .spec & ReconcileAt
  • On refs not found errors, resources weren't explicitly requeue
  • ReconcileAt was not handled at all, even if some types were reacting to it
  • The Stalled condition was added even if the controller could recover on the next try
  • Fix: Receiver webhooks revert apiVersion of ImageRepository to v1alpha1 #328

- Extensively document the various Receiver types, their validation
  mechanics and their caveats.
- Move various things around a bit to ensure we follow the same flow
  as the rewritten source-controller specs.
- Explicitly document the expected format of the Secret.
- Various other small rewordings and fixes.

Left comments about two minor fixes in the docs.
Overall LGTM!

@hiddeco
docs: Rewrite portion of Provider spec
16012ce 
Plus addressing of a couple of nits.

The following must still be picked up at a later moment:

- More sections need to be moved from "working with" to "writing a ..."
- Documentation flow can likely be improved once the sections have been
  moved.
- Technical description of the behavior of the Provider types could be
  improved, this should be easier to do when everything has the same
  format.
