1732: Simplify Travis workflow r=Anviking a=KtorZ

# Issue Number

<!-- Put here a reference to the issue this PR relates to and which requirements it tackles -->

N/A

# Overview

<!-- Detail in a few bullet points the work accomplished in this PR -->

- removed the haddock export, this is taking a huge time and has become a pain in the *** for a very small added value. It can be moved later to a nightly if really needed.
- Still fetches the artifacts from Hydra, this should now be quite quick.
- And, still automatically export the API documentation from the swagger file, latest and pinned versions on releases.
