Rename Licenses API to License Templates API

## What does this MR do?

Earlier I renamed this in EE, thinking license templates was an EE-only feature. This backports that change to CE. Thanks to @vsizov for pointing out this error.

See https://gitlab.com/gitlab-org/gitlab-ee/merge_requests/400 for the EE merge request.

Fix check for existence of New Branch button on Issue page

## What does this MR do?

The condition in [`initCanCreateBranch`][initCanCreateBranch] mistakenly checks `$container` (the New Branch button) for falsy. However JQuery returns an empty array if no matching element was found, so this condition is never met.

## Why was this MR needed?

The wrong condition causes:
* `$.getJSON($container.data('path'))` to be called where `$container.data('path')` is `undefined`
* in this case `$.getJSON` uses `location.href`
* if the current page has a JSON representation, it is fetched and cached by browser and displayed the next time the page is visited (#17365)
* otherwise "Failed to check if new branch can be created" is displayed (#17264)

## What are the relevant issue numbers?

Fixes #17264 and #17365.

Better debugging for memory killer middleware

This adds more info to the warning messages output by `MemoryKiller`.

Previously only the PID was showed, making it difficult to debug issues like https://gitlab.com/gitlab-org/gitlab-ce/issues/19124

This adds the worker class and job ID to the log messages.

See merge request !4936

Image sizing

## What does this MR do?

Limits image height to fit the screen. The wrapping div is so the image is guaranteed to be a block element without the link area growing to be larger than the image itself.

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

Make sure this can't be done in a more performant or concise way with Banzai.

## Why was this MR needed?

Images were displayed at their full resolution, which made it difficult to read issues when the image height was greater than the viewport height (see #18861).

## What are the relevant issue numbers?

Fixes #18861.
