Get-AzureRmResourceGroup and Remove-AzureRmResourceGroup throws ArgumentException if resource does not exisit

[hovsepm]

Repro:

Get-AzureRmResourceGroup –Name 'CdvKeyVaultResourceGroup' –Location 'West US'
Get-AzureRmResourceGroup : Provided resource group does not exist.
At line:1 char:1
+ get-AzureRmResourceGroup –Name 'CdvKeyVaultResourceGroup' –Location ' ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : CloseError: (:) [Get-AzureRmResourceGroup], ArgumentException
    + FullyQualifiedErrorId : Microsoft.Azure.Commands.Resources.GetAzureResourceGroupCommand

Expected: Get[/Remove]-AzureRmResourceGroup should return an empty result if resource group does not exist.

Lets fix this.

@TianoMS - Can you please take a look?

[TianoMS]

@hovsepm I checked the other cmdlets on how to handle similar cases, and the practice seems to be throwing exception.

Get-Process -Id 1234, throws ObjectNotFound exception.
Get-AzureRmSubscription -Id "non-existing-Id", throws PSArgumentException.

I think I'll resolve this one as won't fix.

@TianoMS we should fix it in the other places as well. PSArgumentException/ArgumentException is wrong.

Fixed in 1.6.0
