Can we role the IceRole into the IceConfig and call it IceParameters?  That will
match ORTC a lot more.

In fact, I think it might make sense to make a CL that creates SetParameters
with role+receive_timeout and then this CL can just gather policy and will be a
much smaller CL.

No, based on offline discussion.
