Add support for MongoDB 4.x synchronous/legacy driver

Initially reported in our forum

Our current support for MongoDB is limited to 3.x version of the driver.

https://mongodb.github.io/mongo-java-driver/4.1/driver/getting-started/installation/

There are two variants of the driver to support:

• mongo-driver-sync
• mongodb-driver-legacy (probably close to 3.x driver)

Driver/Server Compatibility matrix

Also, there is also a newer streams-based driver that should probably be covered with a separate implementation issue. https://mongodb.github.io/mongo-java-driver/4.1/driver-reactive/

EDIT: As mentioned in the comments below, there is also another variant for which we might have to check or add proper support: https://mvnrepository.com/artifact/org.mongodb/mongodb-driver-core

@SylvainJuge Thanks for the update. I am excited to test the snapshot version.

Hi @aaqibjavith , we don’t have an exact timeline for this:

• stack releases ship when they are ready, thus we don’t communicate a release date on them to ensure proper quality & prevent frustration when it’s delayed.
• agent releases are not 100% synchronized with stack releases, thus we might get it done either before or after 7.12 release.
• in this repository, milestones are used to indicate which time frame we aim to deal with issues.

When we start working on this, would you be interested in testing a snapshot version to ensure your use-case is properly covered ?
