    yes it is still required, but this PR does address a similar issue.
    
    #4109 limits the size of the operator name in the metric identifier. This was a problem
for all reporters, because a 200+ character name just isn't manageable.
    
    This PR limits the size of all components of the metric identifier for DropwizardReporters,
as the backends of several subclasses store metrics in files, with each component being one
directory., like "taskmanager/abcde/job/myjob/task/mytask". Since they are used as names for
directories they mustn't exceed a certain size (commonly 255). While technically a value close
to 255 would suffice, i figure that anything above 80 characters isn't really well manageable
as well.
