Hi John, thanks for the patch. Few comments: 1. I can't apply the patch against master top,
there is conflict in pom.xml. 2. Could you remove the unnecessary change in ConfigurationManagerImpl
file?

a configured S3 object store. It also pushes snapshots to the object store when they are created
and downloads them in other zones on-demand. In addition to permitting the use of commodity
or IaaS storage solutions for static assets, it provides a means of automatically synchronizing
template and ISO assets across multiple zones.

 I have verified that it does not interfere with normal CloudStack operations when S3-backed
Secondary Storage is disabled (the default setting) .  I have successfully tested operation
of single zone template and ISO scenarios on devcloud described in the design document.  I
am currently working through some issues in our multi-zone test environment to complete all
scenarios described.  The following are the known deficiencies of the current implementation
which I plan to correct in a subsequent patch:
> 
>    * Cross zone garbage collection: When a global asset is deleted from one zone's secondary
storage, it is not deleted from the secondary storage of other zones which have downloaded
it from the object store
>    * S3 Configuration Update: The API only supports adding an object store configuration.
 Users should be able to edit the access key, secret key, connection timeout. max error retries,
and socket timeout.
>    * Multi-threaded Uploads: Permit the upload of multiple assets to the object store
simultaneously to decrease the propagation latency across all zones.
