Collection of changes and scripts needed for the solution of the SCEC benchmarks.

  • Add support for backslip to quasi-dynamic earthquake solver
  • Fix initialization of the system, ensuring that the rate-and-state equations are compatible with stresses

@victorapm for this physics solver, which uses this MGR strategy, the boomer AMG setup crashes in parallel during setup. Without the filter everything seems to work fine.

The case that I have been using to debug it is: https://github.com/GEOS-DEV/GEOS/blob/develop/inputFiles/lagrangianContactMechanics/LagrangeContactBubbleStab_FixedSlip_smoke.xml and you can reduce the size to :
nx = 4 and ny = 2 and still reproduce the issue. A partition of -x 2 is sufficient to trigger the crash.
