servicecontroller: use consistent node criteria
We have two node selection functions: includeNodeFromNodeList and
getNodeConditionPredicate, and the logic is different.
The logic should be the same, so remove includeNodeFromNodeList and just
use getNodeConditionPredicate everywhere.

servicecontroller: remove unused zone field
The zone field was unused, and this complicated e.g. #39996
```release-note
NONE
```
The servicecontroller documents that the master is excluded from the
LoadBalancer / NodePort, but this is broken for clusters where we are
using taints for the master (as introduced in 1.6), instead of marking
the master as unschedulable.
This restores the desired documented behaviour, by excluding nodes that
are labeled as masters with the new 1.6 labels, even if they use the new
1.6 taints.

bump log level on service status update
ref: https://github.com/kubernetes/kubernetes/issues/38349
I tried to reproduce the problem in #38349 and failed. Not sure why service status update failed and service controller skip status update in the next round. What I have observed is that if service status update failed due to conflict, the next round of processServiceUpdate will correct it.
Bumping log level to get a better signal when it occurs.
Many providers need to do some sort of node name -> IP or instanceID
lookup before they can use the list of hostnames passed to
EnsureLoadBalancer/UpdateLoadBalancer.
This change just passes the full Node object instead of simply the node
name, allowing providers to use the node's provider ID and cached
addresses without additional lookups. Using `node.Name` reproduces the
old behaviour.
