network and time config updates for ubuntu 13.10

- new time config module for getting/setting timezones
- updates to network module to work around bug in 13.10
- add debug capability
- 'always' flag to allow a setting to always be applied (even if current setting == previous)
From friday conversation. This module and vars will drop into lib/Service/Time/Timezone. Or, I can take the time and create a Host bucket and move Locale under it, and this can be put under as Host/Timezone. But, may be more changes than we want to consume for the moment.
