Recent commit changed access rights on cassandra.yaml from 644 to 600

    Update cassandra.yaml ownership after write_config operation

    Reasons:
     - Cassandra service fails to start due to changed permissions
       of cassandra.yaml, this was caused because new file was
       created by another user, so it is required to revert
       ownership to conf file to prevent bootstrap failure.

    Changes:
     - adding exec that reverts ownership
       right after config movement.
     - adding exec that sets required permissions

    Change-Id: I6baf86c0070067fae2003f074e3f536a7fad8f5f
    Closes-Bug: #1415862
