Improve the efficiency of modifying job properties in large batches

[nixilin]

In some cases, I have to modify jobs' properties such as add/modify/remove build parameters, set other properties about some job. if some not more than 5 , I can handle it by hand. otherwise I have to find other quick ways to implement it. I tried <JENKINS_INSTANCE_URL>/script , write script to fetch jobs and modify its' properties( ref: javadoc.jenkins.io) , but it's not stable. So I hope there is an officially recognized way to do this. Thank you.
