fix platform driver breakage due to python3 upgrade and fix load minigraph errors with config load_minigraph -y
**- How I did it**
added python3-smbus to the pmon docker template since the previous was python2 specific
fixed additional "ord" python2 specific code
fixed the jinja templates used by qos reload - the template logic required data to be parsed
**- How to verify it**
run "show platform XXX" commands and verify output
run "sudo config load_minigraph -y" and verify configuration
run "show interfaces XXX" and verify output
