> 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.
