--------------------------------------
Making it something that can be set in yarn-site for apps to pick up would be
the simple way. Otherwise it would introduce extra fields in protobuf messages
on AM registration, AMs to handle the absence of the field on older versions,
tests for all of this, etc etc. A documented YARN property is something that
management tools can trivially add, apps can simply read
> YARN should suggest a heartbeat interval for applications
