Takashi Kajinami d7400b5dc4 Add optional healthcheck middleware
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.
