The positional arguments of create flavor is incorrect disposal

[zhangyanzi]

The positional arguments of create flavor name, ram, vcpus and disk are incorrect disposal.
when i create flavor without name ,
it throws exception with message: "name is not a string or unicode"
but i didn't input name ,
I think it should throw exception with message:
"Invalid request body" or
 "The server could not comply with the request since it is either malformed or otherwise incorrect."

The parameter ram, vcpus and disk have the same problem.

    Check compulsory flavor create parameters exist

    Check that the name, ram, vcpu and disk parameters exist
    in the request for flavor creation in order to be able to
    return a more informative error message to a user when they
    are not supplied.
