feat(v1.1): Implement new /health endpoint for v1.1

[OpenStack Infra]

https://review.openstack.org/76555

Dear documentation bug triager. This bug was created here because we did not know how to map the project name "openstack/zaqar" to a launchpad project name. This indicates that the notify_impact config needs tweaks. You can ask the OpenStack infra team (#openstack-infra on freenode) for help if you need to.

    feat(v1.1): Implement new /health endpoint for v1.1

    The new /health endpoint of v1.1 is different from the /health
    of v1.0. In v1.1 /health endpoint we will return a set of KPI
    (Key Performance Indicator) of the target Marconi server. The
    API response will be like below:
