Subject: [PATCH] Connect to mongo db 4.0.x using mongoose 5.7.0

Added support for connection setting useUnifiedTopology so it can be positioned via the database.json file in strapi project. By default it is positioned to false.
If this is not set and you are connecting to a mongo db v4.0.x using the beta-16.1 and higher version of the strapi-hook-mongoose you will get the following warning message when starting the strapi server:
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.
