Update QNameFactory caching

This eliminates the use of soft references in favor of weak ones,
so that we do not rely on GC heuristics for retention.

We also make the maximum cache size runtime-configurable via
org.opendaylight.controller.cluster.datastore.node.utils.qname-cache.max-size
property.

Finally we use QName.intern() to defer to the global QName cache,
resulting in better QName instance sharing.
