  - Merge "[COMMON] Use common secret template in dgbuilder"
  - [COMMON] Use common secret template in dgbuilder

    Taken into account how "easy" it would be to modify the dgbuilder
    which is written in JavaScript (which is not my mother tongue to say
    the least) let's try to remove hardcoded passwords from config files
    without modifying the application container itself.

    In order to achieve this:

    1) Remove createReleaseDir.sh script from the container as it is never
    used and contains a ton of passwords

    2) Replace all sensitive values in config files with references to
    respective environment variables

    3) Introduce init container that will run envsubst command on config
    files and copy them from ConfigMap value to the new volume which is
    backed by tmpfs so that the plain text passwords are never written to
    the disk

    For now all the hardcoded values are still there to minimize the risk
    of breaking the deployment but step by step they will be removed in
    next commits.
