Supportability Doc change: Edge Servers in Active Directory Domain

One of our customers in reading the documentation found they were likely to be blocked as the content here: https://technet.microsoft.com/en-us/library/gg398123.aspx  states

• Edge Servers must be deployed in a workgroup rather than an internal domain. Setup prevents you from deploying Edge Servers in an Active Directory domain.

That statement is incorrect and we will be updating the content to reflect that this is supported.

We still recommend the use of a workgroup or a DMZ only Active Directory to avoid opening ports to the internal domain.
