Hi [~leftnoteasy]

YARN-4106 the Timer related fix for loading conf every interval is done.
So this jira cann't completely replace the same.

Only the heartbeat resend is common between both the jira's. YARN-4106 only 
failed we used to handle in this failed or success we are sending label along 
with heartbeat.

> This JIRA is for handling the below set of issue
> # Distributed nodelabels after NM registered with RM if cluster nodelabels 
> are removed and added then NM doesnt resend labels in heartbeat again untils 
> any change in labels
> # NM registration failed with Nodelabels should resend labels again to RM 
> The above cases can be handled by  resync nodeLabels with RM every x interval
> # Add property {{yarn.nodemanager.node-labels.provider.resync-interval-ms}} 
> and  will resend nodelabels to RM based on config no matter what the 
> registration fails or success.
