------------------------------------------------------------

It seems to be duplicate with YARN-3116

We want to do the same thing, but for the other purpose: triggering the timeline collector
only on for the AM container on NM.

> YARN-2022 adds a flag in RMContainer to indicate whether the container is an AM or not
to skip pre-emption of AM containers. This JIRA proposes propagating this information to NMs
as it's required by the AMRMProxy (YARN-2884/YARN-3666) to identify if the container is an
AM for:
> 1) Security - for authorizing only AMs to communicate with RMs. For e.g.: this is useful
to prevent DDos attacks by all containers of a malicious app.
> 2) Federation - to allow for transparently spanning an app across multiple sub-clusters
