This entailed configring the classifier to never sync on a
schedule.
Changing environment_timeout to unlimited for all masters.
Setting a postrun command for r10k that would update the class
information in the classifier (the update-classes endpoint).
I now have a virtual hierarchy level for setting up my lower memory
settings when using vagrant/virtualbox.
The gms settings are in an example-puppet-master.yaml file in the
nodes directory which are needed for the instructions.
