Confirm Form or setting to Hide option Delete Job in Schedule Tab

[ryanfigueiredo]

Today, on the example screen, when the configuration: Resque::Scheduler.dynamic = true, the option to delete the job in the schedule tab is activated without any security confirmation on click. I need to be able to have the dynamic scheduler and have the option to hide or not the delete job button. From what I saw in the issues and PR there is nothing about it. Would it be possible to open a PR with this request?
