v2.3.0

This release is suitable for mainnet and testnet.

New features:

• guardiand now maintains state for all active guardian nodes. The admin list-nodes command displays detailed info on node status, and corresponding GetCurrentGuardianSet and GetLastHeartbeats RPC calls were added. The old streaming output with on-the-fly aggregation is still available via admin list-nodes-stream.

• Heartbeats now contain a boot timestamp to calculate uptime.

• Heartbeats now include an error counter.

• Prometheus metrics now include network-wide metrics via wormhole_network_node_height and wormhole_network_node_errors_count.

• The example Grafana dashboard was updated for Wormhole v2.

Bugfixes:

• --statusAddr now works (thanks @winslyn!)
• A bug related Ethereum and BSC guardian set fetching was fixed.
