IRB Code for test KRAFDBCK-9927

test mostly complete, added some helpful functions for Expedited Approval 
The code in this step probably needs to be added as a functional method in the data object instead of left at the step definition level.  Then this step's code could be simplified to something like:

@irb_protocol.add_amendment

Also, "I create an Amendment" may read too generically ... an 'amendment' to what?

We can discuss this stuff in more detail.  I'd like to know a little more about the context around a protocol amendment.
