Just filed an idea (AURORA-501) for improvements to the underlying {{HostMaintenance}} api.

> Let's make the drain/maintenance commands have a common prefix, preferably something short.  I propose the following in a man page format:
> {noformat}
> SYNOPSIS
>   host_status [-f filename] cluster [host ...]
>   host_deactivate [-f filename] cluster [host ...]
>   host_drain [-f filename] cluster [host ...]
>   host_activate [-f filename] cluster [host ...]
> DESCRIPTION
>   host_status
>     Print the drain status of each supplied host.
>   host_deactivate
>     The list of hosts is marked for maintenance, and will be de-prioritized
>     from consideration for scheduling.  Note, they are not removed from
>     consideration, and may still schedule tasks if resources are very scarce.
>     Usually you would mark a larger set of machines for drain, and then do
>     them in batches within the larger set, to help drained tasks not land on
>     future hosts that will be drained shortly in subsequent batches.
>   host_drain
>     The list of hosts is drained and marked in a drained state.  This will kill
>     off any tasks currently running on these hosts, as well as prevent future
>     tasks from scheduling on these hosts while they are drained.
>   host_activate
>     The list of hosts is marked as not in a drained state anymore.  This will
>     allow normal scheduling to resume on the given list of hosts.
> OPTIONS
>   -f, --file filename
>     Provide a filename (you can specify stdin using "-") containing the list of
>     hosts to perform the given action on.  No hosts performs nothing.
> {noformat}
