  - Merge "[COMMON] Optimize common secret template"
  - [COMMON] Optimize common secret template

    It turned out that our current implementation of common secret
    template is really heavy which makes onap linitng extremely long.

    To improve the situation let's introduce some results caching instead
    of processing templates over and over.

    For now we cannot simply replace common secret template because in
    mariadb-init we generate list of secrets on the fly so we will need
    to revisit this fragment later.

    Whole series of patches managed to reduce ONAP linting time to 40
    mins.
