[Feature]: Automatically end_user creation

[bgeneto]

The Feature

It would be super nice if LiteLLM could automatically add end-users to the database (EndUserTable) every time a request having a 'user' param is received and the user is not in LiteLLM_EndUserTable table:

INSERT INTO public."LiteLLM_EndUserTable" (user_id, blocked)
SELECT '[email protected]', false
WHERE NOT EXISTS (
    SELECT 1
    FROM public."LiteLLM_EndUserTable"
    WHERE user_id = '[email protected]'
);

This way the UI tab (Usage --> Customer Usage) would automatically show to end_user spend log.

We can make it an optional feature via env var, something like: AUTO_CREATE_END_USERS """

Motivation, pitch

The UI tab (Usage --> Customer Usage) would automatically show to end_user spend log. Since there is no API endpoint to query a spend by 'end_user', this could be valuable.
