This change allows uses to enable the healthcheck middleware from oslo.middleware in API pipeline, by setting the [healthcheck]/enabled option. This middleware provides an API endpoint at /healthcheck path which allows load balancers or monitoring applications to determine a service is up using HTTP requests. This change basically follows the same change merged in ironic[1] repo. [1] 6f439414bdcef9fc02f844f475ec798d48d42558 Change-Id: Ic2ee2bca74ea2a5a0723ef54b10c531f77ea7b8d
