Convert MPI error type to PETSc error with string message for all MPI calls

Now PETSc examples will ONLY return PETSc error codes and never MPI error codes directly so we can understand and post-process their
errors better.

The test harness will now automatically retry tests that fail with MPI, this may help with Intel MPI that produces
seemingly random failures.

Two fixes for petsc_harness.sh and gmakefile.test

petsch_harness.sh:
1. Ensure that -C works. Initial implementation required full paths
and that broke tests from installation directory.
This now works with relative paths

2. Enable the printcmd functionality to work with valgrind and cudamemcheck.

gmakefile.test:

Change search arguments

Based on suggestions from tutorial:
+ `search -> gmakesearch`
+ `globsearch -> search` or `s` (as in `s='dm*plex*'`)
Help updated and cleaned up as well.

That occur after the cuSPARSE library must have been loaded since the load command already succeeded

Add specific PETSc error flag for GPU not having resources available

Try three times to initialize CUDA/cuBLAS and cuSPARSE before erroring. This is for GPU tests that sometimes fail since the GPU

Remove extraneous fields in inverse dictionary in `query_test.py`
Fixes Issue #696
Reported by: @haplav

Add new capability in `petsc_harness.sh` to allow script to compile executable
This improves the workflow of running the script directly by
passing the `-C` flag which then invokes the make target for
compiling that executable.
