archunit-dependency-tests - Prepare branch

Migrates DependencyTests to ArchUnit.
The tests are currently failing due to various undesired dependencies. The tests start with something like: JavaClasses importedClasses = new ClassFileImporter() ... .that(onlySpringData()) By adding .that(ignorePackage(org.springframework.data.aot.hint)) or .that(ignore(SomeClass.class)); the given classes or packages can be ignored for the analysis. Of course the goal should be to fix the cycles.

+== Upgrading

-The 4.0 MongoDB Java Driver does no longer support certain features that have already been deprecated in one of the last minor versions.

-| `<mongo:mongo-client />`
-| Used to create a `com.mongodb.MongoClient`
-| Now exposes a `com.mongodb.client.MongoClient`
-
-| `<mongo:mongo-client replica-set="..." />`
-| Was a comma delimited list of replica set members (host/port)
-| Now defines the replica set name. +
-Use `<mongo:client-settings cluster-hosts="..." />` instead
-
-| `<mongo:db-factory writeConcern="..." />`
-| NONE, NORMAL, SAFE, FSYNC_SAFE, REPLICAS_SAFE, MAJORITY
-| W1, W2, W3, UNAKNOWLEDGED, AKNOWLEDGED, JOURNALED, MAJORITY

-| `<mongo:mongo-client credential="..." />`
-| Single authentication data instead of list.
-
-| `<mongo:client-options />`
-| `<mongo:client-settings />`
-| See `com.mongodb.MongoClientSettings` for details.
