Seems there is no additional comments about implementation, so I just
send cosmetical changes treating comments from previous reviews.

Changes since v3:
- Remove tabs.
- Move Home Services explanation from commit message to comment.
- Add missing ChangeLog-style commit body.

Andrew Tropin (4):
  home-services: Add most essential home services
  home-services: Add home-run-on-change-service-type
  home-services: Add home-provenance-service-type
  home-services: Add fold-home-service-types function
