SSVM ntps do not take custom config

[Yordan Kostov]

Dear all,

                ACS 4.15.2 + XCP-NG + Template 4.15.1.
Trying to change default  SSVM NTPs to internal ones.
                Edit ACS parameter ntp.server.list, rebooted ACS and SSVMs but 
NTPs stay the same.

                Same issue was experienced on 4.15.0 + template 4.15.0 with the 
following github issue opened https://github.com/apache/cloudstack/pull/5160
                Any idea why change is not applied?

Regards,
Jordan
