data-partition-service-0.1-bp153.1.15

Fixes for bsc#1100868:
  - Update data_part.service dependencies to enforce very early
  execution. So it does not collide with cloud-init growpart.
  - Update create_data_part script to verify disk before creating
  any partition and if the disk has been expanded update the
  partition table.
  - Fix an lsblk command typo in create_data_part.

- Make it filesystem-independent
- Fix errors in description
- Simplify %files list
- Use systemd-rpm-macros instead of pkgconfig(systemd)
- BuildReq coreutils

- Include GPL License file

- Initial commit, related to fate#323874
