Migrating from kedro 0.18.4 to the latest version involves handling the deprecated OmegaConf loader. Switching over does not look as bad as I originally thought.

1. installing kedro 0.18.5+
2. set the CONFIG_LOADER_CLASS in settings.py
3. swap out import statements
4. config must be yaml or json
5. getting values from config must be done with bracket `__getattr__` style not with `.get`
6. any Exceptions caught from Templated config loader will need to be swapped to OmegaConfig exceptions, similar to #3
7. templated values must lead with an `_`
8. Globals are handled different
9. OmegaConfig does not support jinja2 sytax, but rather a `${variable}` syntax
