HTML escape xml tags in EC2 responses.

[Roland Hochmuth]

XML escape characters "<" and ">" don't appear to be converted to "&lt" and "&gt" and probably should be.

The code that look like a possible problem is nova/api/faults.py

        resp.body = str('<?xml version="1.0"?>\n'
                         '<Response><Errors><Error><Code>%s</Code>'
                         '<Message>%s</Message></Error></Errors>'
                         '<RequestID>%s</RequestID></Response>' %
                         (utils.utf8(code), utils.utf8(message),
                         utils.utf8(ctxt.request_id)))

Also see bug 978439 which might be a duplicate, might fix both in one shot.
