I feel a major source of issues this plugin faces is how it stores global config in every job. What it should do instead is reference the global config in the Jenkins runtime. Job config should only contain settings related to the job.

This has caused issues in the past like updating global config not properly propagating to all jobs. As we move to slack-2.0 and beyond I could see this causing problems even more. As issues are opened related to this I'll link them to this issue.

If anybody feels like tackling this issue I welcome contributions!
