Certain jclouds-karaf commands cache System.out

I found that the following jclouds-karaf commands cache the System.out object:

• BlobListCommand
• BlobMetadataCommand
• ContainerMetadataCommand

Specifically, the following happens:

   private static final PrintStream out = System.out;

And the reference is subsequently used when printing the output. This is problematic, as a caller may modify the System.out with System.setOut and observe that the output is not pushed to the expected stream/file descriptor.
