Fuel masters' ntp.conf contain settings for both Local Refclocks types

[Kalashnik Dmitry]

Existence of settings for both, Undisciplined Local Clock and Orphan Mode, can provide unstable ntp behavior.
For example unavailability of self-sync in case of isolated cluster:

As long as we don't use (and will not) master node in HA mode, I think that we should just to remove tos orphan string from ntp config.

Fix proposed to branch: stable/5.1

6.x series doesn't vulnerable to this bug due to using new NTP puppet module.

    Delete tos orphan from ntp.conf

    Due to misnomer 'tos orphan' option with local undisciplined clock
    it had deleted from config.
