Add ChamberElastanceInductor to configure

[alexkaiser]

Use Case

The calibrate program currently does not modify parameters in the Chamber blocks. I would like to automatically calibrate the chamber parameters in an LPN.

Problem

This will allow users to tune parameters in more of the existing blocks automatically.

Solution

The function update_gradient should be added to ChamberElastanceInductor.cpp. Code to include the chamber should be added to calibrate.cpp.

Alternatives considered

An initial attempt that does not yet work is in https://github.com/alexkaiser/svZeroDSolver/tree/chamber_calibrate. This fails, at least in part, because parameters are time dependent in the block and the calibrator does not update time like the solver does. I opened a separate issue for updating time-dependent parameters, #139, because that is a more general need than that of adding chambers to calibrate.
