Add :preparing status to HasStatus

Introduces a new status for builds between :created and :pending
that will be used when builds require one or more prerequisite
actions to be completed before being picked up by a runner
(such as creating Kubernetes resources before deploying).

The existing :created > :pending transition is unchanged, so
only builds that require preparation will use the :preparing
status.
