> 1.When RM performs master-slave switching, NM will re-register, report the 
> list of running apps, and print the number of running apps
> 2.registerWithRM#containerReports is enough to print the number of prints, 
> because the above calling process has already printed the container list, so 
> there is no need to repeat printing
> 3.Use placeholders to display logs to avoid string concatenation
