Currently, our core and side module dependent on each others. and will cause
cycle import in our codebase, especially in issue #10905, we try to refactor
to solve this problem.
This patch do the following change:
* Rename module `side` to `models`
* Move `core/base` and `core/sidebase` to dir `modules`
* Move `configuration` and `default_config.yaml` to the root of pydolphinscheduler
Add a new method to get config from environment variables
and for now, we have three ways to get config and the
priority is `env-var > custom-config-file > built-in-config-file`.
Environment config setting does not work in CLI, because it will
confuse users when they get config value is `var-env` but value
in the configuration file is `var-in-file`, they may not find
the way how to change it

* Add it to UPDATING.md

* Refactor configuration.py module
* And file.py to write file locally
* Add more tests on it

* Fix file error when param create is False
* Fix error logic

* [python] Add config mechanism and cli subcommand config
