Avoid Tower in notifications for embedded ansible

[blomquisg]

ManageIQ should not indicate that anything "Tower" exists when dealing
with Embedded Ansible. This should change the logs and notifications to
use a more "embedded ansibly" term when talking about embedded ansibly
things.

Before:

"The operation Ansible Tower Credential creation (name=...) on
Tower(manager_id=...) completed successfully."
^^^^^

After:

"The operation Ansible Automation Inside Credential creation (name=...)
on EMS(manager_id=1) completed successfully."
   ^^^

@blomquisg can you update the spec tests to match the new notification string?
