This commit harmonizes the dependency management of internal modules
so that versions can be omitted everywhere. Update the maven coordinates
to provide the full groupId for consistency
Update `GroovyCompiler` and `AetherGrapeEngineFactory` to use the
recently added `spring-boot-dependency-tools` in favor of loading
dependency information from a generated properties file.
Add a gradle `ResolutionStrategy` that resolves missing version numbers
using the `spring-boot-dependencies` POM.
This commit also introduces a new `spring-boot-dependency-tools` module
that provides programmatic access to the `dependencyManagement` section
of the dependencies POM.
Fixed gh-262
