Jarv/add edx ansible to int

Jarv/nginx ssl

By setting NGINX_ENABLE_SSL ssl this will be enabled in
the nginx configuration for those roles that support
it, currently just the lms and cms.

To use a custom key/cert set the following vars:

* NGINX_SSL_CERTIFICATE
* NGINX_SSL_KEY

Note that there is only one ssl certificate and key
per nginx install, this is because of the way nginx
is setup (independent of the other roles).

We could enable it for different roles though they would
share the same certificate.

Adds ability to have multiple named access logs be rotated

Add curl to rbenv’s debian packages

rbenv install requires curl or wget, if none of them is installed, the

Create log directories after rsyslog is installed

Those directories are created with 'syslog' as owner, if rsyslog is not
installed yet, the user does not exist.
