> Uber jobs fail to update AMRM token when it rolls over

> When the RM rolls a new AMRM master key the AMs are supposed to receive a new 
> AMRM token on subsequent heartbeats between the time when the new key is 
> rolled and when it is activated.  This is not occurring for uber jobs.  If 
> the connection to the RM needs to be re-established after the new key is 
> activated (e.g.: RM restart or network hiccup) then the uber job AM will be 
> unable to reconnect to the RM.
