Option to provide a custom logger

[Algram]

Goals

1. Have a common logger for our whole stack
2. Be able to filter out certain kinds of logs or enhance them with more information

Non-Goals

No response

Background

The current logging solution in next-auth is not suited if you want to enrich the logs or adapt them to your specific needs. Especially in larger organizations with a lot of traffic, this can mean that the only option to get rid of logs or change the level of information provided is to patch the package itself.

Proposal

We should be able to provide a custom logger object/function in the next auth config. All logs should then go to that function.
