System.py for Fugaku

[dyokelson]

Test system setup with:

benchpark system init --dest fugaku-system fugaku 

Visually validate files created in fugaku-system directory

Run an existing experiment:

benchpark experiment init --dest saxpy-test saxpy +openmp
benchpark setup ./saxpy-test ./fugaku-system workspace/

Will update qws for testing the new way as well, but best to use one we know works first to validate the system definition, then we can validate the new benchmark styles on fugaku.
