Make the discussion part on Merge request page optional to see

Description

Some merge requests contain a lot of messages which takes forever to load the whole page. In some cases, I am not interested in ongoing discussions, so why should I wait until all of them are loaded.

Proposal

The idea of this proposal to add make seeing of discussions below the description optional. How it is implemented is up to discussion, from my side I have 2 approaches:

1. Add a button, so if I want to see the discussion part I push the button "Load the discussion"
2. Load description part first, allow a user to see it and in the background, load left discussion part.
