Port eos tests to network_cli (#33586)

* Add eos and fix tests to run multiple connections

* Update tests to report connection

* Add missing START messages

* Fix unspecified connection

* Python 3 updates

Exceptions don't have `.message` in Python 3

* Override `become` when using `connection=local`

* Slight restructuring to make eapi easier later on

* Move eapi toggle to prepare_eos
* Pull out connection on eapi tasks
