    Bump default tox env from py37 to py38
    
    Python 3.8 is now our highest level supported python runtime.
    This updates the default tox target environments to swap out
    py37 for py38 to make sure local development testing is
    covering this version.
    
    This does not impact zuul jobs in any way, nor prevent local
    tests against py37. It just changes the default if none is
    explicitly provided.
