• adding deprecated labels to "legacy" source types

[invincibleJai]

@matzew thanks for updating it, with this containerSource will get deprecated as we only have containersources.sources.eventing.knative.dev for containerSource and not containersources.sources.knative.dev

[matzew]

@invincibleJai on 0.13 there is ONLY the containersources.sources.eventing.knative.dev - that was marked as deprecated in fav. of the sinkbinding. (original idea around 0.13 release cut).

I wrote a migration guide:

• https://github.com/knative/docs/blob/master/docs/eventing/migration/sinkbinding.md

However, there was lot's of noise, disagreement and bikeshed.

With the result that in 0.14 it got added back:

• see the PR for details: Bringing ContainerSource back knative/eventing#2824

Note: It did "re-introduce" in containersources.sources.knative.dev API group
