Use response.text for returning unicode EC2 metadata

When serving meta-data that contains unicode, use the webob Response.text
instead of Response.body.  This also adds a test that triggers the bug in
addition to testing that all meta-data offered by the server can be served.

Closes-bug: #1380792
