It should be possible to run integration tests against docker without sudo

[apostasie]

Description

Currently, -exec sudo is required when targeting docker for integration tests.

It should be possible to test without that.

There are currently issues preventing it - most of them around systemctl w/o --user, but also some tests assuming you can manipulate from the host any filesystem resource controlled but the daemon.

Or if this is not desirable, we should check and fail immediately if not root.
