/**
This Script loops through all your Jenkins jobs, and reports all the jobs, where the configuration of the logRotator,
is out of standard.

This print out each Job in the format ${jobName} DaysToKeep {daysToKeep} #builds ${#number of builds for the job}
and in the bottom a total count of wrongly configured jobs.
Parameters:
_________________
 daysToKeep > The number of days that you wish to keep logs and build info
 adaysToKeep < The number of days to keep artifacts
