Merge "Cache optimizations for setting parent-refs"

Cache optimizations for setting parent-refs

https://git.opendaylight.org/gerrit/49907 introduced a few DS reads which
are not very optimal. This adds couple caches to eliminate/optimize those
reads.

This also removes CacheInterfaceConfigListener and CacheInerfaceStateListener.
There are already clustered listeners for same path.
So we move cache updates to these listeners than using separate listeners.
