Quoting healthcheck command breaks healthchecks in tripleo

[Grzegorz Grasza]

The change that added quoting the healthcheck commands [1] breaks healthchecks in tripleo.

For example, the nova_compute service is configured with a healthcheck that looks like this:

            "Healthcheck": {
                "Test": [
                    "CMD-SHELL",
                    "\"/openstack/healthcheck 5672\""
                ]
            },

other services, that report healthy don't mind the additional quotes, ex:

            "Healthcheck": {
                "Test": [
                    "CMD-SHELL",
                    "\"/openstack/healthcheck\""
                ]
            },

I tested that this issue is present when tripleo is deployed with oooq from master and stein, and reverting this patch fixes the issue.
