[chef] Push jobs server 1.1.6 released

[Yvonne Lam < >]

Ohai everyone,

We have released push-jobs-server 1.1.6 to fix an issue in which unsigned packages for push-jobs-server 1.1.5 [1] caused its installation to fail. This is a point release because we also had to upgrade a test dependency on mixlib-shellout 1.6.0 [2]. There are no other changes between push-jobs-server 1.1.5 and 1.1.6.

Installation directions for push-jobs-server: https://docs.chef.io/install_push_jobs.html
