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.

use a common function to determine account ID instead of different

* Switch to use io.open() for py3 compatibility and simpler testing.
* Open files in 'rb' mode to avoid translation on Windows

Previously tests simply relied on files that were present in the
repository to run tests using open().  Change the filenames to ensure
that no longer happens.

requests_mock doesn't have a way to match against the request body for
PUT/POST; an attempt to add a new Matcher to do that worked but it
needs to subclass the currently private adapter._Matcher class or
duplicate most of its functionality.

api.object_store.APIv1 now contains the formerly top-level functions
implementing the object-store REST client. This replaces the old-style
ObjectClientv1 that is no longer necessary.
