[Rdo-list] Keystone eventlet vs WSGI

[Charles Short]

ok thanks for the info.

I have written a post install script for now that seems to work which 
turns the Keystone eventlet into WSGI and alters Pacemaker accordingly.

For smoother deployment I will wait until the stable branch has this 
integrated  as my Puppet Fu is also lacking

Regards

Charles
