Provide a standard API for health checks of containerized services

Registered by Lars Kellogg-Stedman on 2017-05-17

An OpenStack deployment involves many services spread across many hosts. It is important that we provide tooling and APIs that make it as easy as possible to monitor this large, distributed environment. The move to containerized services in the overcloud (https://blueprints.launchpad.net/tripleo/+spec/container-healthchecks) brings with it many opportunities, such as the ability to bundle services with their associated health checks and provide a standard API for assessing the health of the service.
