Add a new state ABORTING.
This makes transitions from normative states to error states explicit
in the STM, and serves as a disambiguation for which states may complete
normally when normal end-states (CONCLUDED) are added in future commits.
Notably, Paused/Standby jobs do not transition directly to aborting,
as they must wake up first and cooperate in their cancellation.
Transitions:
Running -> Aborting: can be cancelled or encounter an error
Ready -> Aborting: can be cancelled or encounter an error
Verbs:
None. The job must finish cleaning itself up and report its final status.

# The job may return to @ready or otherwise be canceled.

+# @aborting: The job is in the process of being aborted, and will finish with
