  - Merge "[DMaaP MR] Remove "lost+found" in kafka PVC"
  - [DMaaP MR] Remove "lost+found" in kafka PVC

    When using a storage class, kafka data is set on top of a partition and
    then 'lost+found' ext4 folder, which is automatically created, is seen
    as a topic but with bad naming.

    So we remove this folder in the init script.
