> The NodeManager should provide a way for an AM to tell it that either the
> logs should not be aggregated, that they should be aggregated with a high
> priority, or that they should be aggregated but with a lower priority. The
> AM should be able to do this in the ContainerLaunch context to provide a
> default value, but should also be able to update the value when the container
> is released.
> This would allow for the NM to not aggregate logs in some cases, and avoid
> connection to the NN at all.
