Swift authentication via the Cloudstack API.

------
SETUP:
------
File: proxy-server.conf
Add 'cs_auth' (and 'cache') to your pipeline:

    [pipeline:main]
    pipeline = catch_errors cache cs_auth proxy-server

Optional S3 Integration - To add support for s3 calls, change the above to:

    [pipeline:main]
    pipeline = catch_errors cache swift3 cs_auth proxy-server
    
    [filter:swift3]
    use = egg:swift#swift3

Add account auto creation to the proxy-server.

    [app:proxy-server]
    account_autocreate = true


Add a filter for 'cs_auth':

    [filter:cs_auth]
    use = egg:cs_auth#cs_auth
    cs_api_url = http://127.0.0.1:8081/client/api
    cs_admin_apikey = <admin user's apikey>
    cs_admin_secretkey = <admin user's secretkey>
    swift_storage_url = http://127.0.0.1:8080


------
USAGE:
------

Curl:
-----
Request for authentication
curl -v -H "X-Auth-User: $cloudstack_username" -H "X-Auth-Key: $cloudstack_apikey" http://127.0.0.1:8080/v1.0
returns: $cloudstack_auth_token and $cloudstack_swift_storage_url

Request container list
curl -v -X GET -H "X-Auth-Token: $cloudstack_auth_token" $cloudstack_swift_storage_url


Swift CLI:
----------
Request status
swift -v -A http://127.0.0.1:8080/v1.0 -U $cloudstack_username -K $cloudstack_apikey stat


S3 API:
-------
Requires the optional step in SETUP
(example uses the python boto lib)

from boto.s3.connection import S3Connection, OrdinaryCallingFormat

conn = S3Connection(aws_access_key_id=cloudstack_apikey,
                    aws_secret_access_key=cloudstack_secretkey,
                    host='127.0.0.1',
                    port=8080,
                    is_secure=False,
                    calling_format=OrdinaryCallingFormat())
bucket = conn.create_bucket('sample_bucket')
