Merge branch 'dz-bulk-edit-mr' into 'master'

Add bulk update support for merge requests list

## What does this MR do?

Adds new feature: ability to update multiple merge requests at once from index page (same like we have for issues already)

## Are there points in the code the reviewer needs to double check?

I don't think so

## Why was this MR needed?

* consistency with issues
* save user time when you want set same label/milestone to 20 merge requests
