Enable deployment of availability monitoring

Registered by Martin Mágr on 2016-07-22

TripleO should have a possibility to automatically setup and install the availability monitoring stack (Sensu and Uchiwa) to service the overcloud.

All components of the availability monitoring will be deployed by TripleO using Heat+Puppet. The sensu-server, sensu-api and uchiwa services will be deployed on a stand alone node deployed by the undercloud, with a dedicated purpose for all optools (not only availability monitoring, but also performance monitoring and centralized logging in future).
The Optools node will be deployed as a separate Heat stack to the overcloud stack.

The sensu-client service will be deployed as a composable role on the overcloud stack. Sensu checks will be configured as subscription checks (see [1] for details). Each composable service will have it's own subscription string, which will ensure that checks are run on the correct overcloud nodes.

Gerrit topic: https://review.openstack.org/#/q/topic:ooo/opstools/sensu

(shardy) +1 on the general ideas here, but I think there are some interactions between the current undercloud sensu integration, composable services and custom roles which would benefit from some discussion, could you please draft a spec where we can discuss this in a bit more detail please?
