/health endpoint returns wrong status when cassandra is offline

[Malini Kamalambal]

Steps to repro:
Start poppy server with no seed values for cassandra.
Do a GET on /health endpoint

Expected Result:

{
    "storage": {
        "cassandra": {
            "online": "false",
            "links": {
                "href": "http://XXXX/v1.0/health/storage/cassandra",
                "rel": "self"
            }
        }

Actual Result:

{
    "storage": {
        "cassandra": {
            "online": "true",
            "links": {
                "href": "http://XXXX/v1.0/health/storage/cassandra",
                "rel": "self"
            }
        }
    },
    "providers": {
        "fastly": {
            "online": "true",
            "links": {
                "href": "http://XXXXX/v1.0/health/provider/fastly",
                "rel": "self"
            }
        }
    }
}
