Set carnegie local relative to carnegie secure, so we have to get the
prefixes right once only.

They have their own LMS DB.

If the nginx play is called with the nginx_conf varialble, then expect
to find in {{secure_dir}}/files/nginx.conf and copy it over.  If not set
then the default one already there will be sufficient.

One comes with the standard installation, overwrite with our own,
provided in {{secure_dir}}/files.

To support variations on our local LMS sites files it is helpful to have
subdirectories where we can store variations.  At Stanford I'm using
this so I can store carnegie/lms.j2, a variation on our normal lms.j2.

To use you can call the role like this:
    - {'role': 'edxapp', 'openid_workaround': true, 'template_subdir': 'carnegie'}
This would be from your main playbook file, in my case
edx-west/carnegie-prod-app.yml.

While in here I noticed we weren't setting owner or perms on the
sites-available/XX files, fix that.

edx-west staging playbook/config file update

Restore direct modulestore

add edx-west/.gitignore for symlink to config repo

Not checking those symlinks in since they are symlinks to another repo,
but generally people will want these.  On my machine they look like
this:
    configuration-secure@ -> ../../../configuration-secure
    edx-secret@ -> ../../../configuration-secure

Just for the edx-west configuration files.

Rename edx-platform version variables

edx-west/{prod,stage}-jumpbox: barebones playbooks

Feanil/vpc tools

Remove references to cms update_templates

Just to facilitate user updates to the jumpboxes.

* attempts to fix race condition where rabbitmq guest user addition was
  failing
