[Rdo-list] HA document using application-native tools and keepalived, updated for Kilo

[Javier Peña]

Dear all,

Following the RDO Kilo release, I have updated the document describing
an architecture for a highly available OpenStack setup using
application-native options and keepalived.

As part of the update, instructions for Sahara and Trove have been
added, and several smaller details have been fixed. You can find the
updated document at
https://github.com/beekhof/osp-ha-deploy/blob/master/HA-keepalived.md .
Of course, the Juno version is still available in a separate branch.

Feedback (and PRs) are welcome. I expect to add detailed scenario files
using phd (https://github.com/davidvossel/phd) in the future, but that
is currently work in progress.

Thanks,
Javier
