ci: 1411 implement version

[pawelpasterz]

Fixes #1411

Implement Version class (and related logic) to handle dependencies versioning

Test Plan

How do we know the code works?

1. run

    git checkout master &&\
      ./gradlew clean assemble &&\
      ./gradlew dependencyUpdates -DoutputFormatter=json -DoutputDir=. &&\
      java -jar ./flank-scripts/build/libs/flank-scripts.jar  dependencies update &&\
      git diff >> dep_master
   

2. run

   git checkout . &&\
     git checkout 1411-implement-version &&\
     ./gradlew clean assemble &&\
     ./gradlew dependencyUpdates -DoutputFormatter=json -DoutputDir=. &&\
     java -jar ./flank-scripts/build/libs/flank-scripts.jar  dependencies update &&\
     git diff >> dep_version
   

3. compare dep files

   diff dep_master dep_version
   

4. there should be no differences (nothing is printed to the console, exit code = 0)

Checklist

• Unit tested
