Today, aborting a maintenance compaction like major, which is waiting for
its turn to run, can take lots of time because compaction manager will
only be able to bail out the task once it gets the "permit" from the
serialization mechanism, i.e. semaphore. Meaning that the command that
started the task will only complete after all this time waiting for
the "permit".
To allow a pending maintenance compaction to be quickly aborted, we
can use the abortable variant of get_units(). So when user submits an
abortion request, get_units() will be able to return earlier through
the abort exception.
