Date format of published content view in yaml output changed on Rails 5.x and causes Puppet runs to fail
Calling to_yaml on an instance of ActiveSupport::TimeWithZone gives different output on Rails 4.2 and 5.x (see the screenshots), which makes Puppet run fail. Katello adds a date of a published content view into the output of Host.info method. When Puppet tries to fetch the node definition and yaml contains a date in a new format, Puppet server fails to parse it.
Steps to reproduce:
1) set up a host with Puppet and published content view
2) try running puppet agent -t
3) observe the error
