Upgrade Heat

This could possibly use gold plating in how bootstrapping
operates to use shade rather than the shell in the container.
It is unclear why stack create failed prior to this patch, but
that fact hasn't changed.  I think the heat domains are not setup
properly in the configuration files, meaning that the domain ID
must be created outside of Heat and registered in the configuration
file.  This is covered in Bug #1553565.
