MAR-127: Implemented time synchronisation set-up in common role:

- Added new parameter ntp_servers for defining list of servers to use.
- Deploy ntp and ntpdate packages and relevant configuration files.
- Updated tests, fixing expected restriction lines in ntp
configuration, and adding an additional test to make sure the ntp
daemon has reread its configuration.
