Add simple method for setting time zone vs lookup via API

[gwblok]

Problem: Currently to set the Time Zone, OSDCloud does a lookup of an API, which uses the IP Address of the machine running OSDCloud to determine the time zone it is in. This works great unless you're a large organization sharing an internet IP with multiple time zones.

Request: Provide method of passing a time zone into the process to have OSDCloud set.

Options:

1. Drop down in the GUI with Time Zones (Similar to ConfigMgr)
2. Pre-Set a TimeZone Variable that will be used

Notes from Gary:

Option 2 will be the first option (of the 2) implemented in OSDCloud vNext, so I'd guess sometime in Q4 No plans to implement option 1, as most orgs that would need this option should be using automation and variables vs the GUI anyway. Places that use the GUI typically are smaller in nature, and the current method using the API should be good enough.
