James E. Blair 79807e11a1 Change mycloud.com to example.com (RFC2606).

From RFC2606:
   To reduce the likelihood of conflict and confusion, a few top level
   domain names are reserved for use in private testing, as examples in
   documentation, and the like.

Currently the documentation contains URLs that point to mycloud.com,
which is registered and not affiliated with OpenStack.  It's better
to use example.com which exists for this purpose.
