Simplifying decryption

Features

@ryantm and @jsimonetti #119:

Simplify decryption by combining the root and nonRoot secret decryption into one Activation Script and delays setting the owner and group of the secrets until after the users and groups activation scripts are completed.

• This is a breaking change for someone that depended on the user or group of a root secret being set before the "users" and "groups" Activation Scripts run.
• This is also a breaking change because it renames a bunch of the Activation Scripts. The new activation scripts are:
  • agenixInstall: does the decryption of secrets
  • agenixChown: changes secret users and groups
  • agenix: an Activation Script that can be depended on to ensure your Activation Script runs after all agenix operations have completed.
• Also this fixes bug inherent to the old system's order of operations #117 reported by @jsimonetti.
