@Samrat002 The purpose of this pr is to increase the printing of the number
of running apps and avoid the repeated printing of container information. From
my personal point of view, I think it is better to use placeholders for
printing logs, so I modified it.

> 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
