MongoDB adapter

[Totodore]

This is a tracking issue for a mongodb adapter. Once the async adapter PR is merged (see #395) it will be possible to start working on a mongodb adapter. For the db driver, it seems that the official mongodb driver is the default go to lib: https://lib.rs/crates/mongodb.

Starting to work on it

Nice, I encourage you to start on the async-adapter branch to get upstream modification on the Adapter interface. Also if there is any blocking point, enhancements you can specify them on the PR #395.

You can also check the redis-adapter branch (#402) to have an implementation example (WIP).

I was doing wrong;
I was implementing the traid Adapter in socketioxide::adapter::Adapter. I thought that the LocalAdapter is one of the adapters and we could extend it from there and add the adapter in this function SocketIo::builder().with_adapter<MongoDBAdpter>()
I will follow your RedisAdapter example
