Fix missing import in helm_deployment_status.py

After recent changes a regression emerged due to
not properly imported 'subprocess' module 'check_output'
function.

Predefined list of available healthcheck modes is also
removed to allow passing any mode that will be supported
in future by healthcheck script.
