This reverts commit f093129b32.

Reason for revert: This is breaking all airshipctl and treasuremap gate runner job. The issue is that, the services added here creates some dependency to time sync and few other services and due to which cloud init is stuck in running state forever. Please fix this issue and update a new PS with dependencies resolved.
