[clock] auto-selection of time source
This patch introduces a new time source named 'auto'. When
--time_source flag is set to 'auto', the system's behaves is the
following:
* If the host is of known cloud instance type that provides
a dedicated NTP server, the time source is set to 'builtin'.
* If the host is of known cloud instance type that doesn't provide
a dedicated NTP server or the host is not recognized as a cloud
instance, the time source is set to 'system'
(if 'system' time source is supported, otherwise set to
'system_unsync').
In former case, if the --builtin_ntp_client_enable_auto_config_in_cloud
flag is set to 'true', the built-in NTP client is configured to use
the dedicated NTP server provided by the cloud platform.
