upgraded target platform to newer MongoDB driver from org.eclipse.orbit;

A 3.x driver is required to connect to Microsoft Azure Cosmos. Upgrading
the target platform accordingly requires further upgrades, including Hamcrest
and JUnit libraries. This, in turn, deprecates or obsoletes numerous APIs,
parts of which that caused compilation *errors* I've replaced by their new
counterparts. Several more warnings still remain and need to be tackled by
replacing the usages to their new counterparts.
