LogRotator set globally on the instance

As a Jenkins administrator, I'd like to be able to set the logrotator on the jobs on my instance. I'd like this value to be "read-only" on the jobs, so the users of my instance cannot change it. This way, I'm sure that the space usage of the builds is handled correctly.

Today, it is possible to use the configuration slicing plugin to "re-apply" this logrotator configuration on the jobs from time to time. However, this task is time-consuming and having a way to prevent my users to change this value on the job configuration would be a more reliable solution. 

Another solution would be to have the value set globally, and accept the users to change it on the job level, but the global value would act as a default value at the job creation time.
