1) Change metadata to appear under a common 'properties' key, and
use the utility to format them, this applied to object, account
and container.
2) Clean up container and object output, which were setting the
x-container-meta-owner property, but this is metadata only for
the container, so it's pointless to have, removed it.
3) Container show was showing read/write ACLs and sync stuff, but
these are not being returned by my swift by default, so I moved
these to be checks, so we don't clutter the output.
