This mirrors work done in other OpenStack projects to add systemd notification support to signal that a given process is ready to accept requests. The heat-api, heat-api-cfn, heat-engine, and heat-api-cloudwatch processes are all covered by a new, single, 'onready' configuration file option. Additionally, the sample configuration file has been updated to match. Implements: blueprint systemd-integration Change-Id: I90d2b915e2568a65ed9ed78923c9982e19f9c948 Signed-off-by: Lon Hohberger <lhh@redhat.com>
