Migrate Calibration Code to New Random Service Interface

Migrate Calibration code to use the new interface
of the random number generator service designed to work
with the multithreaded Framework. The main interface
change is to require a StreamID or LuminosityBlockIndex
argument to the getEngine function. These objects are only
available during the event or beginLuminosityBlock method.

There is only one calibration module using the random
number interface. I do not know how to test this module
as nothing else in CMSSW references it.
