UPSTREAM: <carry>: Consolidate build API

This consolidates the in-cluster building of a bundle and catalog.
The catalog and bundle bindata are inputs, along with a set of
replacements so that catalog and bundle templates can be used to
create the images.

This can be done in the BeforeEach() for a set of tests that use the
same data.
