Ceph REST API WSGI wrapper

ceph-rest-api.wsgi

'''
WSGI wrapper for the Ceph REST API to be run behind Apache with mod_wsgi.

Place this script in /var/www as ceph-rest-api.wsgi and use this VirtualHost:

<VirtualHost *:80>
    DocumentRoot /var/www
    ServerName ceph-rest-api

    ErrorLog /var/log/apache2/error.log
    CustomLog /var/log/apache2/access.log combined

    WSGIScriptAlias / /var/www/ceph-rest-api.wsgi
</VirtualHost>

You have to specify a Ceph configuration file to use, that will be used
to detect which monitors to connect to and which keyring to use.

A sample Ceph configuration:

[global]
    keyring = /var/www/ceph.client.admin.keyring
    mon_host = 1.2.3.4,2.3.4.5,3.4.5.6
    log_file = /dev/null

Make sure that the configuration file and keyring are readable by the webserver.

Logging has to be disabled, otherwise librados will try to create a logfile
in /var/log which is not allowed by when running under the webserver's user.

Now go to http://localhost/api/v0.1 and you should see the API!

Tested with:
- Ubuntu 14.04
- Apache 2.4 (apache2-mpm-worker)
- mod_wsgi (libapache2-mod-wsgi)
- Python 2.7.6
