Perhaps before merging this, let me look into adding Pod resource options that can be passed to zk-operator and etcd-operator as well.

I would probably change the name pod to solrPodPolicy, since we have been namespacing the solr properties with Solr. And there are other pods in the pipeline, such as the busybox pod, so it makes sense.

But this is definitely something I've been wanting to add myself, nice job!

Let me know when you've made a decision on this front

@HoustonPutman we should be good to go with this now. How does it look? Added etcd, zetcd and zookeeper pod policy (resources and affinity) options. Tested out all locally and works as expected! Let me know what you think. If we merge this, I can work with @swarupdonepudi to rebase his PR with my changes here.
