Define Jenkins Jobs via Jobs DSL

This will allow for creating all jobs from a groovy script in a seed job. Saves time and allows you to restore jobs when configuration is incorrect.

Create Seed Job called SeedJob

• Go to New Item
• Name it SeedJob and choose Freestyle project and go to Ok
• Add Build Step Process Job DSLs
• Select use provided DSL script, paste in groovy script from JOB_DSL and Save
• Go to Manage Jenkins and go to In-Process script approval to approve the new groovy script
• Go back to Build Now on Jenkins SeedJob.

Once SeedJob builds all default jobs are now present.
