> The client exposes a {{kill}} subcommand to kill jobs, which currently applies to cron
and non-cron jobs.  This is translated into a {{killTasks}} RPC, and the scheduler internally
inspects the query to determine if this is a request to kill a whole job.  Acting on this
RPC for a job means that the scheduler attempts to transition a slew of tasks to {{KILLING}}
state.  This is benign, but inefficient and can result in lots of log noise.
> In the short term, the scheduler should restrict non-cron job-scoped kills to only active
tasks.  Longer-term, we should expose a more explicit way for the client to ask for a cron
job to be unscheduled.
