Option to change log format to JSON

First off, thank you for putting in the work. This is a super helpful project.

I would appreciate it if it was possible to enable an option besides LOG_WITHOUT_NEWLINE and DISABLE_REQUEST_LOGS to have one line per request in the log output formatted as JSON.

One of the reasons is that I don't use the logs on the host machine directly. They might get scraped and processed out of order by Loki, so they might not end up next to each other. The second reason is that it would be simpler to parse them when they had the same format.

Comece localizando as opções existentes LOG_WITHOUT_NEWLINE e DISABLE_REQUEST_LOGS e rastreando o caminho de logging das requests. Adicione um formato JSON selecionável que emita uma linha por request e, em seguida, verifique se a saída pode ser analisada consistentemente e preserva as informações de log solicitadas.
