Add option -ts_trajectory_memory_type

- Add dev changes
- TSTrajectoryMemory: further savings for stiffly accurate schemes
- TSTrajectoryMemory: namespace private functions
- TSTrajectoryBasic: when the solution is the same as the last stage, no need to save both of them to disk.

Add matrix-free example for ex5adj and clean up ex5 examples

- Delete duplicative code for the ease of maintenance.
- Update output for the examples

Add interface to libcams

- CAMS also work for stiffly-accurate methods. The last stage points to the solution vector ts->vec_sol. This feature is leveraged in CAMS checkpointing to reduce the memory

Add interface to libcams

- CAMS also work for stiffly-accurate methods. The last stage points to the solution vector ts->vec_sol. This feature is leveraged in CAMS checkpointing to reduce the memory cost.

- Add option -ts_trajectory_max_units_ram
- Added -ts_trajectory_max_units_ram and -ts_trajectory_max_units_disk to specify the number of available checkpointing units.
- Conceptualy a checkpoint may contain multiple checkpointing units (solution and stage values) of the same size.
- Users should use either max_units or max_cps, but not both at the same time.

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.
