Mitogen IO

Description

Todo:

• Do not use the existing url based approach. Create a set of entities that represent the different methods (local, ssh, sudo, su, docker, podman, ...) and include the via concept.
• Test this approach on a resource like fs::File
• Cleanup the exception handling (see also mypy output) that was "hacked" from the existing io https://code.inmanta.com/solutions/modules/mitogen/-/blob/poc/inmanta_plugins/mitogen/init.py?ref_type=heads#L121
