Puppet has a bultin feature to schedule when resources get applied. However, there is some awkwardness with using this feature as it doesn't apply to a class and only to the individual types in the class. I want the ability to schedule an entire class with foreman.

I would like to be able to schedule an event that adds class(es) to a host/hostgroup/environment/.... This would be very helpful so that I could "auto add" classes during our scheduled maintenance window.

For example.

at 3AM on Sunday add the following classes to the default hostgroup.

class: apache-upgrade
class: memcache-upgrade
class: kernel-upgrade
