Set the Ready condition on the composite

[stefnans]

What problem are you facing?

Thanks to crossplane/crossplane#6021, we can now explicitly set the ready condition of the composite resource. It would be useful to be able to set this ready condition for the composite resource with function-go-templating (unless there's already a way to do it that I'm missing?).

How could this Function help solve your problem?

I was thinking we could have a similar annotation to gotemplating.fn.crossplane.io/ready: "True", but for composite resources as well. This means having in the template a metadata section for the composite (which can be confusing since we are not supposed to manipulate the metadata and spec section of the composite resource) that will be removed after the render like we do for composed resources.

Totally agree, @stefnans! Would you like to work on a PR for that?

[stefnans]

Thanks @phisco. I'll give it a go as soon as I have time.

If someone already wants to take a crack at it, please do.

Here is a PR implementing this feature #446

One problem is that it relies on crossplane/function-sdk-go#218 and thus may be delayed until the next release of https://github.com/crossplane/function-sdk-go
