Update nodeStatuses info when a pod is recreated

[olim7t]

#638 added the ip and rack fields to nodeStatuses. However this information is not correctly refreshed when a pod is deleted and recreated: the pod IP might change, but the status keeps returning the old IP.

I think this is because I made the changes inside of the if force || nodeStatus.HostID == "" { ... } block. It's probably just a matter of moving them a couple of lines below.

On a side note, it would also be useful to have the CQL port alongside the IP, we can use the opportunity to add it (unless there is a reasonably easy way to infer it from the DC spec).

On a side note, it would also be useful to have the CQL port alongside the IP, we can use the opportunity to add it (unless there is a reasonably easy way to infer it from the DC spec).

We don't allow changing CQL port at the moment in cass-operator, that work would be relevant to ticket: #242 and requires changes in the port definition codes, which are hardcoded everywhere, like:

cass-operator/apis/cassandra/v1beta1/cassandradatacenter_types.go

Line 811 in 3dfaadc

namedPort("mgmt-api-http", 8080),

cass-operator/pkg/reconciliation/construct_service.go

Line 32 in 3dfaadc

namedServicePort("native", nativePort, nativePort),

So that would be a PR of it's own, requiring design how all the port definitions can be modified, tested, wired to the mgmt-api and supported there also (I'm not sure how much mgmt-api even supports these).
