MT#58395 new python based ngcp-update-db-schema script

* ngcp-update-db-schema is rewritten in python. that simplifies
  the code, as well as enables flexibility and more complex features
  support, as well as performance improvements
* full strict mypy compliant
* flake8 compliant
* google docstring complied
* add .down scripts support
* add docstring full documentation
* add mypy, isort, flake8 checks during build phase
* add command line arguments that support --to-revision, to stop
  .up/.down scripts execution when it reaches a certain revision
* better support for ngcp-sync-db
* preserve AUTOMATED_INSTALL_MODE and SKIP_SYNC_DB env vars support
  for backward compatibility, in the future it is recommented to
  switch to the existing (--automated, --skip-ro-sync-db) options
* experimental batch mode support where instead of applying changes
  one by one, they are accumulated into a file along with db_schema
  revision tracking changes and applied at once
