core: skip node watcher during initial cache sync

When the operator starts, there is no need to handle the
node watcher immediately while the controller runtime
cache is being initialized. The cluster will anyway be
fully reconciled and create new OSDs if needed. The node
watcher is only intended for triggering a reconcile when
a node is added or updated at a later time after a sync
would anyway be triggered.
