The shared module for all the µs of the project/product 
The module is used as sub-module in all the µs of the product and maintains all the shared logic between the µs, mainly in the area of the Build Automation Tool (Gradle and Jenkins in this case).
- Jenkinsfile and Jenkinsfile4Release
- Dockerfile
- branchSpecificConfig.properties - holds the branch unique configuration and utilized by the pipelineCommon.groovy build script
- Gradle related files:
- common.gradle - the main shared Gradle build logic (powering each of the µs build.gradle)
- common.groovy - all the Groovy functions used with the common.gradle file
- Execution environments related configuration (to be injected into the runtime environment):
- .docker (folder) - holds docker related configuration (e.g. config.json file)
- .kube (folder) - holds K8S (a.k.a. kubectl) related configuration (e.g. config file)
- .gradle (folder) - holds the common setup used by the Gradle build in the µs:
- gradle.properties - the common properties used by the common.gradle module (mainly)
- init.gradle - the common initialization logic (initializing each of the µs build.gradle)
