Added performance guidelines for new MRs

## What does this MR do?

This MR adds a set of guides that should be followed by merge request authors.

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

Spelling, grammar, etc

## Why was this MR needed?

There is no set of guidelines one should follow when submitting merge requests. This leads to developers at times disregarding performance. This in turn results in performance specialists having to clean up the mess, or production engineers being woken up in the middle of the night because the database is on fire.

Check for pipelines when setting page_gutter_class.

## What does this MR do?

Fixes regression issue related to the MR window sliding behind the right sidebar on page refresh. 

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

I'm getting stuck thinking about if/how to test this. Or maybe it just deserves a note somewhere about remembering to update `page_gutter_class` when a new route is added?

## Why was this MR needed?

This regression prevented users from using many features of the MR view.

Resize created icon

## What does this MR do?
Resizes `created` SVG

## Why was this MR needed?
Because:
![Screen_Shot_2016-08-30_at_3.33.38_PM](/uploads/c4c987e323b4c9cedeb298f08abbc307/Screen_Shot_2016-08-30_at_3.33.38_PM.png)

Hard-coding in the size into the SVG isn't a great solution, but we've got a bit of technical debt here. All the other icons are sized this way, so for this patch fix I think we should just match it. Ideally we'll have classes directly in the SVG code so we can target all these icons properly, and do all color/sizing through CSS

Remove default value for lock_version

## What does this MR do?

From the very beginning we added `lock_version` column with default value, then we reverted that MR. A bit later we added that migration again but column's default value has been removed from migration. So if you installed GitLab form master it's possible that you have default value, which caused  the bug.

We don't need to change a CHANGELOG here I think.

Fixes https://gitlab.com/gitlab-org/gitlab-ce/issues/21527 and https://dev.gitlab.org/gitlab/organization/issues/971
