Move GapPerfectConductance from BISON to MOOSE

[gambka]

Motivation

GapPerfectConductance is a type of thermal BC used in ThermalContact for non-mortar based contact. It enforces that perfect conductance occurs across the gap by setting the temperature equal on opposite sides of the gap. A penalty parameter, of a sufficiently high value, is required to lead to proper enforcement when in axisymmetric coordinates with small gap widths. Currently, GapPerfectConductance lives in the MOOSE-based app BISON and is almost always created via the ThermalContactAction. Unfortunately, the penalty parameter of the GapPErfectConductance cannot be currently set by the user through the ThermalContactAction. It also doesn't make sense to add the penalty parameter to the action that is housed in moose/modules/heat_transfer when it is only useable by an object in BISON. There is nothing in this model preventing its use in other applications.

Design

Move existing source, tests, and documentation from BISON to appropriate locations in moose/modules/heat_transfer. Add a new test for the small gap axisymmetric case demonstrating the need of the penalty parameter. A patch PR to BISON will be necessary and will be coordinated with the changes addressing this issue.

Impact

People can properly access all input parameters for GapPerfectConductance and appropriately set all input parameters via the input file through the ThermalContactAction.
