This change makes it easier to track queuing sequence and the order in
which builds should be processed.

This ensures that only valid objects can be upserted into the database.

This also ensures that we handle errors in a better way, if we detect
duplicate records. This commit also adds additional tests to cover
multiple failure scenarios related to managing builds queue.

This applies another patch from @abrandl that only adds `created_at`
instead of full timestamps.

This commit adds a pending build model that will create a resource in
the database when a build transitions to the pending state. The resource
will be removed when an associated build gets picked by a runner.

Applied 0001-Minor-tweaks-to-ci_pending_builds.patch from @abrandl.
