Backport of cli: Fix plan diff for sensitive nested attributes into v1.1

This is a backport of the move away from CircleCI from the main branch to the
v1.1 branch, just so we will still have checks when backporting other code
to the release branch.

This is an amalgam of the following commits from the main branch:
