Subject: [PATCH] Reduce cassandra-init image

- remove unnecessary packages (libffi,libxml,curl,perl,npt,apt-transport)
- reduce sdctool.tar archive size (440MB -> 185MB) by excluding artifacts
  that are not used in the init image (zusammen-tools)
- extract sdctool.tar in separate stage to avoid it being saved as it's own
  image layer
- reduces image size from 2.7GB to 750MB

Issue-ID: SDC-4803
Change-Id: I129052200c76906034b6c0ddb89b29ca1dddd89a
