Give an explicit error message if MPI can't be called from a sub-process #18

See #17 . At least OpenMPI 4.0.5 does not allow mpirun to be called from a sub-process.

This PR now gives an explicit error message with the shell scheduler if the MPI implementation can't be called from a sub-process.

Also implement two minor misc improvements :

for the shell and SLURM scheduler, give the absolute path of the error log files
use 3 error classes (to raise usage, environment or internal pytest_parallel errors)

…st if MPI works with sub-processes. Added exception.py
