Further refactoring for multiple NTP servers
Further refactoring to support adding multiple NTP servers in a later
commit. The logic for multiple servers will be added to forceRefresh()
later.
This commit also contains some refactoring to support improved testing
of NtpTrustedTime.forceRefresh(). Tests for the existing behavior have
been added here.
As part of this change, SntpClient / NtpTrustedTime /
NetworkTimeUpdateService have also been extended to pipe information
about the IP address of the NTP server used to obtain the time back to
the NetworkTimeUpdateService for improved logging / debugging support.
