CatLight 2.7 - Jenkins improvements (performance + branches)

We have a new Jenkins adapter implementation in CatLight 2.7. It has several improvements:

• Faster polling times when only small number of jobs is monitored.
• Reduced server load on Jenkins server that has hundreds of jobs.
• Better integration with Multibranch Pipeline and GitHub organization plugins. CatLight will now show branch-jobs as branches. You can select top-level job in monitoring settings, and CatLight will automatically monitor child jobs for active branches. You can fine-tune branch monitoring in global app settings.
