* Merge init_kwargs with env variables recursively to handle nested values
This commit implements `deep_update` function that works as standard
`update` method on dicts, but also recursively updates all the nested
dict values. It allows splitting init arguments between environment
variables and in-code values, as long as they create a valid object
when merged together.
