Add HostID test into Debug-SdnFabricInfrastructure

[arudell]

Description

Summary of changes:

• Added Test-ServerHostId test to Debug-SdnFabricInfrastructure which will cross-compare the InstanceID from the servers resource with the registry key on the Hyper-V host.
• Added additional defensive coding to Debug-SdnFabricInfrastructure and Start-SdnDataCollection to ensure that if we are in a remote runspace session, that if CredSSP is not enabled, we have -Credential parameter defined otherwise terminate with critical error.
