Reference to IntegrationKit metdata in Builder CR

[lburgazzoli]

looks like the builder cr stores the metadata from the IntegrationKit in a spec field :

metadata:

This seems to be used only by the s2i builder as it has not yet been re-factored as a task, once done, we should remove such reference
