Update git submodules

* Update docs/submodules/oom/offline-installer.git from branch 'master'
  to 171c3dc7dd5a9cdc25651812dc716174c38d5f06
  - Merge "Our bare repos need to have casablanca branch"
  - Our bare repos need to have casablanca branch

    This is required to align with OOM charts, otherwise
    some components like DMAAP might be not initialized
    properly. Furthmore removing duplicated files, most
    of our data_lists are same for Casablanca MR and
    Casablanca base releases.
