Add e2e test

[JacobGros]

Description

This PR adds a e2e test to velero-upgrade branch.
This new test will install AM v1.0.3 and upgrade to v1.1.0. Then it will downgrade AM again.
Adds standalone yaml and sets test file to point to it, to run only this test; we'll need to revert this change before merging velero-upgrade into main, but I left as is in case others want to add/edit tests for velero-upgrade
