BSC_Tests/hopping: add TC_fh_params_assignment_cmd
This test case verifies presence and correctness of the hopping parameters in the following messages and their IEs: 1. (RR) Assignment Command 1.1. Description of the First Channel, after time IE 1.2. Mobile Allocation, after time IE Change-Id: Id12509385b444c426f4af7a0cf0d46efe2cb0eda Related: SYS#4868, OS#4545
