feat(mongodb): Add MongoDB client handshake metadata

[alexbevi]

The PR addresses #626 by incorporating MongoDB's wrapping client library specification for the connection handshake to allow library details to be included in the metadata written to mongos or mongod logs.

For example, this change would allow server-side logs such as the following:

{"t":{"$date":"2024-01-27T23:10:40.108Z"},"s":"I","c":"NETWORK","id":51800,"ctx":"conn16235","msg":"client metadata","attr":{"remote":"127.0.0.1:1094","client":"conn16235","doc":{"driver":{"name":"nodejs|unstorage","version":"4.16.0"},"platform":"Node.js v18.18.2, LE","os":{"name":"linux","architecture":"x64","version":"5.15.133+","type":"Linux"}}}}

For anyone hosting clusters with connections coming from different applications this can help differentiate connections and facilitate log analysis.

I think we should instead support generic mongoOptions as a driver option so you can set it to { driverInfo: { name: "..." } } based on your needs

i agree. we could default if it helps:

// in the top of the file
const defaultMongoOptions: MongoClientOptions = {
  driverInfo: {
    name: "unstorage"
  }
};

// here (where i'm commenting in this PR)
const mongoOptions: MongoClientOptions = {
  ...defaultMongoOptions, // don't bother deep-merging, people can override `driverInfo` as a whole
  ...opts.clientOptions
};

then update the MongoDbOptions to have:

clientOptions?: MongoClientOptions;

and either way, we should strongly type this instead of any

Great suggestions! I've worked these into the PR

Looks good to me 👍

@pi0 I'll leave you to merge once you've had time to read through
