name/id parameters should be consistent

[binderjoe]

Our get commands use a verbose and inconsistent convention for the argument names. For example:
az availabilityset get --availability-set-name [name
az vm get --vm-name

These commands should all just use "name" since the name clearly pertains to the "get" noun. E.g.,
az vm get --name [name]

This should now be consistent across all currently existing commands. As new commands come online, we need to make sure that we alias the parameter names correctly.
