cli, glusterd: Address issues in get-state cli output

This fixes the following data points:
1. Volume type
2. Peer state
3. List of other hostnames for a peer
4. Data unit information for rebalance

The following data points are removed:
1. Mount options and filesystem types for bricks
2. global-option-version from list of global options

The following data points are added:
1. Replica Count
2. Tier type for bricks belonging to hot/cold tier
