Remove old davinci configurable and related tests
Update all the scripts to the new DaVinci configuration. Removing old DaVinci Configuration.py and the related option files and qmtests not used with the new Configuration. Removing also the following qmtests:
- packing.qms/test_dstunpacking_upgrade.qmt: it will be replaced by a new test with !573 (merged).
- davinci.qms/gaudipython_algs.qmt: due to some overlaps with the other qmtests
- io.qms/test_write_dst.qmt: it will be replaced in a future dedicated qmtest
