Metricbeat unable to connect to MongoDB using SCRAM-SHA-256

Hello !

Metricbeat relies on the community GO driver to connect to a MongoDB cluster. This driver is quite old and has been replaced by an official driver.

Since it is now unmaintained, it has not received any updates since the release of MongoDB 4.0. In particular, it does not support the SCRAM-SHA-256 auth mechanism, which we use by defautlt in our cluster.

Are there any plan to migrate metricbeat to the official mongodb GO driver and support more recent versions of MongoDB ?
