quality-code-tests: Refactoring - split run-in-renode.py (#32)

The run-in-renode.py script was split into smaller files
to improve code readability and facilitate later changes.

- action arguments are now converted to json before being passed to the script
- small typo fixes
- replaces sendcontrol('c') with sendline('') in some places
- fixes potential races with git repos sideloading
- adds 1 hour timeout to installing pip packages on target
