Pipeline IID not return on API request
Summary
When accessing the Pipeline API to get the latest pipelines, no pipeline iid is listed.
Steps to reproduce
Make a API Request to get the latest pipelines for any project like the following example:
What is the current bug behavior?
No "iid": parameter was return in the get request. Only the "id": is returned.
What is the expected correct behavior?
The documentation describes that the "iid" is also returned https://docs.gitlab.com/ee/api/pipelines.html
Relevant logs and/or screenshots
Proposal
The team noted that these two areas (1, 2) may need changed to expose that in the GET response.
