We need to be able to release patch version for Camunda Spring Boot Starter.
E.g. after 2.3.0 and 2.4.0 were released, we can release 2.3.1, which includes 2.3.0 + some bug fixes.

1. Job, performing minor release, must create branch for the version that is being released.
2. Release job must be able to take "branch" parameter, so that we can define either "master" or some version branch.
