[Research] Make logging configurable

[Uxio0]

Problem

When we need to see an issue in production, logging can only go from INFO or WARNING to DEBUG.

We need a way to increase the level for only a Service or Task

Solution

Investigate about possible solutions, document them on this issue and open a new issue to implement the solution

Initial ideas

• https://docs.djangoproject.com/en/5.0/howto/logging/#configure-responsive-logging and have some variables like LOG_SAFE_INDEXING_LEVEL, LOG_PROCESSING_LEVEL, LOG_ERC20_INDEXING_LEVEL

Solution

Define logger by groups for example:

#ERC20_LOGGER
       "safe_transaction_service.history.indexers.erc20_events_indexer": {
            "level": env("ERC20_INDEXER_LEVEL", default="INFO")
        },
        "safe_transaction_service.history.tasks.index_erc20_events_task": {
            "level": env("ERC20_INDEXER_LEVEL", default="INFO")
        },

Where ERC20_INDEXER_LEVEL will define the log level for everything related with ERC20 indexer.

Groups proposed

• ERC20_721_INDEXER_LOG_LEVEL
• PROXY_FACTORY_INDEXER_LOG_LEVEL
• SAFE_EVENTS_INDEXER_LOG_LEVEL
• INTERNAL_TX_INDEXER_LOG_LEVEL
• API_LOG_LEVEL (all the endpoints)
• BALANCES_API_LOG_LEVEL
• MESSAGES_API_LOG_LEVEL
• ALL_TRANSACTIONS_API_LOG_LEVEL
