[GeoMechanicsApplication] Add integration point to extrapolation process to geomechanics application

[mcgicjn2]

Through the use of element shape functions, the extrapolation matrix for an element can be calculated. Through this extrapolation matrix the gauss values on a single element can be extrapolated to the nodes. These values should then be averaged for the number of connecting elements.

Acceptance Criteria:

• A user would like to calculate gauss\integration point values on the nodes of the mesh. (Typically for visualization)
• The process should be able to make this calculation for all available element types
• The process should be efficient
• The process should be fully tested
