Pull request overview
This PR updates the core time sync test suite to skip verify_timesync_ptp on older Ubuntu and RHEL versions where Azure’s documented PTP/chrony configuration isn’t expected to be present, avoiding false failures on those OS releases.
Changes:
- Import
UbuntuOS type to allow distro-specific gating in the test. - Add OS version checks to skip
verify_timesync_ptpon Ubuntu< 19.10and RHEL< 8.0.

On Ubuntu >= 19.10 and Red Hat Enterprise Linux >= 8.x, chrony is configured to use a PTP source clock.
Older Linux releases use the Network Time Protocol daemon (ntpd), which doesn't support PTP sources.
