YARN-6766 added HelperMethod for AppsBlock Class

[riyakhdl]

YARN-6766

Description of PR

The various *AppsBlock classes are riddled with statements like:
.append(appInfo.getReservedVCores() == -1 ? "N/A" : String.valueOf(appInfo.getReservedVCores()))
The code would be much cleaner if there were a utility method for that operation, e.g.:
.append(printData(appInfo.getReservedCores()))
