Review request for cloudstack.


Chiradeep, here are the diffs against current master. I also made some internal changes to
S3CAStorBucketAdapter to support "domain" and "zeroconf" in configuration.


Below is the commit message. This is my first patch, let me know if I did anything wrong or
if e.g. using "storage.root" is not how configuring a new storage backend should be done.

Add initial support for Caringo's CAStor object storage as the S3 backend.

Similar to the s3-hdfs example. Now storage.root can specify "castor"
followed by a list of IP addresses for the nodes in the CAStor
cluster. S3 operations will then create and read buckets and objects
in CAStor instead of a file system.

Tested a boto script I believe we got from Chiradeep ( that creates buckets
and streams, does a range read and delete. I will continue to do more testing (
