Keep track of selected Hyper-V switch using the ID instead of name
to prevent any encoding issues that may occur switching between
PowerShell and Ruby. With the IDs staying consistent, the switch
name can be fetched from the provided ID.
Fixes#9679#8794#9451
+ This disambuguates calls to the Hyper-V functions for the Hyper-V provider.
The ambiguity of some commands - such as `Get-VM` - causes the Hyper-V provider
to fail on systems where VMware PowerCLI is installed. This change ensures that
all calls to Hyper-V specific cmdlets or functions are prepended by `Hyper-V\`.
This ensures the correct cmdlet calls are being made.
+ Resolves #8862.
