Nginx X-Forwarded-For header configuration.

The nginx configuration was set to pass X-Forwarded-For and related headers
unodified to backend services.
This works fine when nginx is deployed behind another load balancer
(for example ELB), which already properly sets the X-Forwarded-* for headers.

But in simpler deployment scenarios, where nginx is directly facing the end user,
nginx should discard any existing X-Forwarded-For headr and set it to remote IP of the request,
the X-Forwarded-Port header to the nginx server port, and the X-Forwarded-Proto
to the scheme of the current request.

The 'NGINX_SET_X_FORWARDED_HEADERS' is set to False by default, but set to True
in the edx_sandbox playbook, where an additional load balancer in front of nginx
is not usually present.

Add new settings that were added to edx-platform.

Updates to get alton to work on the admin instance.

Splunk improvements

Correct the default version of alton.

This doesn’t need to be a directory, it can be just a file (globing also
works).
See http://docs.splunk.com/Documentation/Storm/Storm/User/Editinputsconf

When downloading the deb from splunk’s website, it doesn’t have that
format.
