Since this file changes rapidly in jenkins and it is difficult to manage
via version control here.  It's hard to maintain the changes made from
Jenkins in sync here, so remove it from git to reduce complexity.

Make the admin files more coherent.

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.

Updating local ec2 module

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.
