feat: Cleanup and Move Python dependencies to virtual environment

[marcelmamula]

Proposal for sap_hana_ha scenario before working on others

Description

• Remove packages that are not needed
• Install pip modules into virtual environment
• Execute sap_launchpad with virtual environment
• Create new python inputs in extravars for python version selection (ansible interpreter is Control node specific and cannot be used)

Tested the task logic successfully in a dedicated playbook just for sap_launchpad.
This worked fine for a new download as well as being idempotent in a re-run.

👍

Would it make sense to clean up the venv afterwards? Assuming that the venv is only needed for the sap_launchpad execution on the software target host, it could be nice to remove it afterwards. Similar to the cleanup of other temporary config like temp dirs or ssh keys.

@ja9fuchs Thank you for suggestion! I have replaced it with tempfile and delete it afterwards

Tested the tempfile change - working nicely. :)
