enable pipe between Get-AzVM and Get-AzVMExtension

[skmkzyk]

Description of the new feature

Currently, Get-AzVM returns VM name with column name 'Name'.
But Get-AzVMExtension requires 'VMName' to specify VM name.
So, below cmdlet pipe is not working for now.

> get-azvm -name ephe01 -ResourceGroupName ephemeral-disks | Get-AzVMExtension
Get-AzVMExtension : The input object cannot be bound because it did not contain the information required to bind all mandatory parameters:  VMName
At line:1 char:60
+ ... m -name ephe01 -ResourceGroupName ephemeral-disks | Get-AzVMExtension
+                                                         ~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidArgument: (Microsoft.Azure...SVirtualMachine:PSObject) [Get-AzVMExtension], Param
   eterBindingException
    + FullyQualifiedErrorId : InputObjectMissingMandatory,Microsoft.Azure.Commands.Compute.GetAzureVMExtensionCommand

Is it happy to enable this type of cmdlet chaining?
This kind of disconnection will be occur other VM extension cmdlets.

Proposed implementation details (optional)

Hi @skmkzyk thanks for your feedback! I'm forwarding this issue to Compute team.

Thanks for the feedback! We are routing this to the appropriate team for follow-up. cc @mjconnection, @Drewm3, @avirishuv.

We will look into this request. Currently the cmdlet Get-AzVMExtension is auto-generated from the API specs. So we will need to augment the auto-generated cmdlet to also support an input object of type Microsoft.Azure.Commands.Compute.Models.PSVirtualMachine.
