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)

Changes support from IE 10+ to IE 11+

IE 11 was released 17 October 2013; 2 years ago. Generally what I have experienced is that support for browsers (when newer ones are available) continues for up to 2 years. Based on that info we would drop support for IE 10 and the latest IE we would support would be IE 11. 

I also think this is more realistic since no one is really testing anything on IE 10 at the moment.  We should start testing on all the browser that we currently support. 

Also we can then have real support for flexbox and not need things like `-ms-flexbox` and other IE specific hacks.
