jamf_pro: ingest pipeline sets host.address field

The ingest pipeline sets `host.address`, but this field is not a defined ECS field. Removal of the field should be considered, but doing so would be a breaking change since there may be users who now depend on it for searches.

Start by locating the jamf_pro ingest pipeline and checking how it maps the non-ECS `host.address` field. Verify the ECS field definition and inspect any pipeline tests or fixtures; done means the issue has a decided, validated treatment of the field and its breaking-change implications.
