Remove legacy duplicate metric classes in helix-core (#1147)

As part of ZooKeeper API separation initiative, most metric-related classes were moved to metrics-common module. However, there were some that were left in helix-core for backward-compatibility purposes, but these were causing class conflicts at runtime. This change removes such classes.

Helix is a generic cluster management framework used for automatic management of partitioned, replicated and distributed resources hosted on a cluster of nodes. Helix provides the following features:

  1. Automatic assignment of resource/partition to nodes
  2. Node failure detection and recovery
  3. Dynamic addition of Resources
  4. Dynamic addition of nodes to the cluster
  5. Pluggable distributed state machine to manage the state of a resource via state transitions
  6. Automatic load balancing and throttling of transitions
