Sanity Tests » no-main-display

As of Ansible 2.8, Display should no longer be imported from __main__.

Display is now a singleton and should be utilized like the following:

from ansible.utils.display import Display
display = Display()

There is no longer a need to attempt from __main__ import display inside a try/except block.
