Force TLSv1.1 or greater when supported (#548)
Force TLSv1.1 or greater when supported (#548)

The Box API will be deprecating TLSv1.0 support in the future, but
Java 7 environments use that protocol by default.  The SDK needs
to force TLSv1.1 or greater to maintain compatibility with the Box
API.  This should work in all supported Java versions (7+).
