[SYSTEMDS-???] Python API startup fixes
This PR change the startup of the python interface to properly use the jar files, and fixes a release issue where if the SYSTEMDS_ROOT is not set the python API did not properly hook into the released jar artifacts.
Still debugging a bit, therefore it is marked as a draft.
@j143 Can you check if this fixes the issues for the release artifacts.
I have tested it with the released code, and it works for me.
If you set the SYSTEMDS_ROOT to the path of the unzipped bin release it works just like the other releases. It also correctly detect the log4j files, in different configurations.
@j143 I decided to merge it, because i have other things that depends on it, Feel free to comment on the Commit directly 387b6c1c8e472dde65a36e8f3fd22091054ed347
