Set the ConfirmImpact of New-Az*Object and Get-* to Low rather than using default value

New-AzObject is a client side cmdlet to create an object. So both new-Azobject and Get-* will not change any thing in service side, so adding shouldprocess with even confirmImpact set to low does not make sense here.
I think we should fix the analyzer instead.

Hi @dolauli , thanks for your opinions. But if we don't set confirmImpact for them, powershell will regard them as high impact in fact, which may cause harm.

Close as add task to improve static analyzer for these two kinds of cmdlets.
