DeprecationWarning: current Server Discovery and Monitoring engine is deprecated

[odin16]

Hello I am working with a mongo connection but I get the following warning:

DeprecationWarning: current Server Discovery and Monitoring engine is deprecated, and will be removed in a future version. To use the new Server Discover and Monitoring engine, pass option { useUnifiedTopology: true } to the MongoClient constructor.

The solution is to add the new option but I'm not sure where, so it is possible in any of the following places:

1. /lib/databases/mongodb.js

• line: 91

  var defaultOpt = {
    ssl: false,
    useUnifiedTopology: true, //  <--- Option 1 for remove warning
  };

2. /lib/databases/mongodb.js

• line: 98

 if (isNew) {
    defaultOpt.autoReconnect = false;
    defaultOpt.useNewUrlParser = true;
    defaultOpt.useUnifiedTopology = true; //  <--- Option 2 for remove warning
    _.defaults(options.options, defaultOpt);
  } else {
    defaultOpt.auto_reconnect = false;
    _.defaults(options.options, defaultOpt);
  }

Can you provide a PR for Option 2?

Excuse me, I've been a little busy and haven't seen your answer. Of course I will do a PR, Thanks.
