Remove reading shell environment in rhel_subscribe

The rhel_subscribe role used to read the shell environment variables for
its input with a broken fallback to Ansible variables.

This updates the role to only use Ansible vars. If the user wants to do
an env lookup, they can do so when calling the role.
