Grzegorz Bizon b9c19f6b0f Do not serialize a pipeline again when showing a build
This change makes it possible to avoid additional serialization of
entire pipeline when rendering a build details page. Instead we expose
more information from the build entity itself what is much cheaper than
serializing entire pipeline.

Additionally we do not need to serialize `latest?` flag, which involves
multiple Gitaly calls.
