Enable gradle dependency locking for all subprojects. This change allows us to use dependency ranges, without loosing reproducible builds.
It also makes it easier for third party services such as snyk to detect dependencies and their versions.
Update Gradle to 7.3. in order to profit from the performance improvement and to prepare for dependency lockfiles. Due to the upgrade to 7.x we had to use a license plugin which supports Gradle 7.
Do not add scm-packaging modules to every build.
These modules drastically increase the time Gradle spends in the configuration phase.
To build a distribution of SCM-Manager pass -Pdistribution.
Upgrade Gradle to 6.8.2.
