of any "non-native" NTP daemon.

This could be a warning-level message but we don't have
such messages from the prechecks.

Closes-Bug: #1885689

Based on the discussions from the past 3 Kolla meetings [1][2][3],
we established that, to avoid the DockerHub pull limit issues
in our CI, we will try using quay.io.

This change applies only to CI.
The user-facing move is yet to be discussed.
