Handle server side default for TrafficDistribution

[rhr323]

This PR fixes a bug related to the TrafficDistribution field that was added to the Kubernetes Service spec (kubernetes/api@0a84c1b).

If the API server defaults TrafficDistribution to PreferClose on Services, this can cause issues since ECK doesn't currently preserve this server-side defaulted value in its reconciliation logic. If ECK removes it and the API server then adds it back, ECK could get into an infinite reconciliation loop.

I confirmed that manually patching the Service – ECK does remove the trafficDistribution field.

Fixes: #8812
