Non action method in controller should be private
Local variables snake_case instead of CamelCase
Use snake_case instead of camelCase for method names
Refactored system template specs

Test now uses factory girl. Also make use of let helper instead of
before each which is lazy evalued. Clean lazy attributes from Repo that
are not used anymore after Pulp v2 migration.
Remove expectations on nil warnings

When running all rspecs somewhere in the middle were displayed warnings
that you are expecting message receive on nil objects. This was caused
by wrong variable names in systems_controller_spec.
Fix ping spec

Headpin ping spec was not set in headpin mode so it tried to contact
Pulp. I DRYed up this spec and added config stubbing so it works
correctly.
