Moving int to str

[ArneTR]

This PR superseeds https://github.com/green-coding-solutions/green-metrics-tool/pull/780 and adds more str conversion for parameters that are allowed as int but must be str due to the nature of GMT shell outs.

Also some comments are added for clarity.

P.S.: This behaviour might be obsolte if we switch to an API based docker container orchestration contrary to the CLI atm
