Make the functions parameterized in order to call the main method
from another python class. Before the methods used a global
variable to access the values.

The load of the program arguments are moved to the main function
call and the rest is extracted into a main function, that get
the needed arguments passed.

Use the parameters -res and -reso to reset the kubernetes cluster.
With -reso only the cluster is resetted in nothing else is executed.
With -res the cluster gets resetted before execution of the usecase.

The order of the environment variables is atm crucial for the
run uc py.

Run uc py still used statefullSet instead of deployment
