[FAB-8986]: Harden gradle build configuration

1. Extract dependencies into parent project.
2. Define source and target java version.
3. Add IDE's gradle plugins
4. Add java and maven plugin to make it possible to execute `./gradlew
build install` to promote resulting artifacts into local maven
repository.
