Django reverse proxy for Grafana SSO

django-grafana-proxy.py

"""
## Install the Django reverse proxy package: `pip install django-revproxy`

## Enable auth.proxy authentication in Grafana like the following

```
[auth.proxy]
enabled = true
header_name = X-WEBAUTH-USER
header_property = username
auto_sign_up = true
ldap_sync_ttl = 60
whitelist = 127.0.0.1
```

The whitelist parameter can be set if Django and Grafana are in the same host.

After that add this line in the Django project `urls.py`:

```
url(r'^dashboard/(?P<path>.*)$', views.GraphanaProxyView.as_view(), name='graphana-dashboards')
```
