[Feature Request] Create service connection with "az devops service-endpoint create" for other Environments like AzureUSGovernment and AzureGermanCloud

**Is your feature request related to a problem? Please describe.**
Not able to specify creation of service endpoint (connection) for Environments other than "AzureCloud," such as "AzureUSGovernment."

**Describe the solution you'd like**
If the --service-endpoint-type is **azurerm** we should also be able to specify the Environment, similar to "az cloud set" command.

**Additional context**
Within the browser interface, the *full version* of the New Service Connection dialog box for Azure Resource Manager allows specifying 4 environments:
- AzureCloud
- AzureUSGovernment
- AzureChinaCloud
- AzureGermanCloud

The CLI should expose these options as well.
