Build out Online Template Registry

[ChrisKibble]

This is the long term goal of the project. Eventually I'd like the module to come with some really basic templates (e.g., domain controller, domain client, etc.) but then templates would be available in a registry online that they could install as packs.

For example, perhaps Lably doesn't come pre-installed with templates needed for SCCM, however they could do something like:

Install-LablyPack -Name "ConfigMgrCB"   # Download Lably Template Pack for SCCM from Online Repository
New-Lably -Pack "ConfigMgrCB"           # Builds DC (using template), SCCM Server (using template), and a client.

And now they'll have templates for building an SCCM Site, WSUS server, database server, etc. The community could contribute (under moderation) to the repository. Perhaps over time we'd allow other registries to be added so that folks could house their own internal repos of templates useful for their project or organization.
