      Description

      There are two things that must be put into systemd units: support for loading BRM from S3 and conditional SM start.
      For the former part we need to introduce a custom BRM loader(preferable in Python) that can choose b/w:

      • S3-backed BRM. This mode supports all kind of installations if SM is configured(more strict condition if it is properly configured)
      • local BRM files. This mode can be used by single-node and multi-node installations with local storages.
      • compare local BRM and get it from the main node(only if needed). This mode must be used by nodes with local storage and w/o controllernode(slave DBRM nodes).
        For the latter part, namely SM conditional start systemd we can rely on a conditional check, e.g. if /etc/columnstore/storage-manager.cnf is not empty.
