Moving the pipeline behavior into its own class resulted
to a lot of breaking changes. Instead, we're just gonna use the same
commit object but just delegate the pipeline related calls to the
CommitWithPipeline instance.

To better isolate and organize the pipeline related behavior
of the Commit object, we extracted them into their own class.

Instead of preloading the status, we now preload the
latest pipelines instead for each commit. This gives us more
flexibility on how to display the status.

This also helps us avoid passing the current_user deep through
the model methods. Best to call the detailed_status in the
view/presentation layer.

Instead of returning just the string value of the pipeline's status,
return the detailed status so that success with warnings are properly
indicated.
