cloud-config supports a new plugin, called 'set-timezone', which can be used to change the timezone on the underlying instance. The patch adds a new method in the osutils abstraction, called `set_timezone`, which should be implemented by each separated OS. The abstraction calls into cloudbaseinit.utils.windows.timezone, another layer of abstraction over two API methods, SetTimeZoneInformation for Windows 2003 and older and SetDynamicTimeZoneInformation, for newer versions of Windows, which also handles Daylight Saving Time. The plugin supports standard IANA timezone names, which are then translated to the Windows-specific timezone names, using tzlocal library. Change-Id: I18674e1ae078fc69f3fb938065ba01a4de5464a1
