 This file is the definition of a Zero module. It contains a list of all the required parameters to be able to prompt a user for choices during `zero init`, information about how to template the contents of the module during `zero create`, and the information needed for the module to run (`zero apply`).
 It also declares the module's  dependencies to determine the order of execution in relation to other modules.
