Load the "New Branch" button asynchronously

Here's how it looks like for logged in users:

![new_branch](/uploads/718e3d9016a50a0432b9541dde5ca74c/new_branch.gif)

And here it is for anonymous users (or when a new branch can't be created by a logged in user):

![new_branch_anonymous](/uploads/dce42ee6a7dd7708443cdfdb56389d46/new_branch_anonymous.gif)

This button depends on Issue#can_be_worked_on? which in turn depends on
Issue#related_branches. By rendering this button asynchronously we can
finally remove all usages of Issue#related_branches and
Issue#referenced_merge_requests from the issues "show" page.

Enable the UrlFormat and UrlQuotes SCSS Linters.

There were no lints to fix for this one, so it's just preventative.

UrlFormat: URLs should be valid and not contain protocols or domain names.

UrlQuotes: URLs should always be enclosed within quotes.

Disable Rack Attack if admin disables it in config file

Grack::Auth already checks this variable. These holdouts were not disabled, leading to confusion when debugging a customer issue.

Use ActionDispatch Remote IP for Akismet checking

Previously all remote IPs appeared at 127.0.0.1, which made Akismet
not very useful. Using the ActionDispatch Remote IP (http://api.rubyonrails.org/classes/ActionDispatch/RemoteIp.html)
should provide more reliable results.

Backport GitHub Enterprise import support from EE

These changes were pulled from GitLab EE to support configuring
an alternative API URL than the default https://api.github.com.
In addition, the `verify_ssl` flag allows users to disable SSL cert
checking.

One modification: add a default `args` option if it does not exist
to avoid breaking existing configurations.

Add JS prefix to user tab classes

## What does this MR do

This MR adds the `js-` prefix to the classes which are used for js purposes only. This MR only affects the said classes inside `users/show.html.haml`.

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

I'm not entirely sure if this project uses the `js-` prefix for
classes that are used for js purposes only. Doing a grep shows some of the classes have the prefix, but I'm still unsure whether this project follows this rule.

## Why was this MR needed?

As I was working thru #13401, I wanted to add a tab on the user profile page to show the contributions outside the GitLab instance. Reading the JS, I came across this. This MR helps new people reading the code that the said classes are for js purposes only. Also, it helps the project work toward to uniform class naming.

I suggest that we document adding the `js-` prefix to classes for js purposes only (if this is the case for this project)
