object storage: Add Ceph RGW support

This commit adds support for Ceph's RADOS Gateway (RGW) support for the
Object Store feature of CloudStack.

The RGW of Ceph is Amazon S3 compliant and is therefor an easy and straigforward
implementation of basic S3 features.

Existing Ceph environments can have the RGW added as an additional feature to a
cluster already providing RBD (Block Device) to a CloudStack environment.
