errors: make InterventionRequired subclass Abort
The docstring for `Abort` says that it's for errors raised by commands
and `InterventionRequired` is definitely something raised by commands,
so it seems that it should be an `Abort`. This patch makes it so. It
adds a `coarse_exit_code` (in addition to the already existing
`detailed_exit_code`) to `Abort` to achieve that, since
`InterventionRequired` should result in a special exit code even when
the `ui.detailed-exit-code` config is not set.
