[RFC-0004] imagerepo: add support for insecure registries

Add a new field `.spec.insecure` to the `ImageRepository` API to allow
indicating that the registry is an insecure registry, i.e. hosted at an
HTTP endpoint. Furthermore, add a new flag `--insecure-allow-http` to
allow the controller to make HTTP requests. By default, it is set to
true to ensure backwards compatibility.

Implements [RFC-0004](https://github.com/fluxcd/flux2/tree/main/rfcs/0004-insecure-http).

+### Insecure
+
+`.spec.insecure` is an optional field to specify that the image registry is
+hosted at a non-TLS endpoint and thus the controller should use plain HTTP
+requests to communicate with the registry.
+
+> If an ImageRepository has `.spec.insecure` as `true` and the controller has
+  `--insecure-allow-http` set to `false`, then the object is marked as stalled.
+  For more details, see: https://github.com/fluxcd/flux2/tree/ddcc301ab6289e0640174cb9f3d46f1eeab57927/rfcs/0004-insecure-http#design-details

 ### Provider
 
 `.spec.provider` is an optional field that allows specifying an OIDC provider
