PowerShell functions are defaulting to AzureCloud, not the cloud they are running in.

I spent a lot of time having issues getting my PowerShell functions to work. What I finally realized is that they thought they were running in AzureCloud when they were actually running in AzureUsGovernment.

A simple suggestion to fix this for future users would be to modify the profile.ps1 file to set the Environment to AzureCloud explicitly. That way there is an obvious setting that needs to be modified.

```powershell
if ($env:MSI_SECRET) {
Disable-AzContextAutosave -Scope Process | Out-Null
Connect-AzAccount -Identity -Environment AzureCloud -ErrorAction Stop
# Get-AzSubscription -SubscriptionId -ErrorAction Stop | Set-AzContext -ErrorAction Stop
}
```
