Changing image name. The image is currently under `/tun/cloudflared/cloudflared-daemon/master`. We want to instead have it under `/tun/cloudflared/cloudflared/master`. Adding the `daemon` suffix does not add much value.

In addition, our acceptance tests should now be able to use the latest image instead of relying on a fixed version for testing, which will allow us to detect potential failures earlier.
