 - Added a new RPC endpoint `/v3/health` to query the node's health status. The endpoint returns a 200 status code with relevant synchronization information (including the node's current Stacks tip height, the maximum Stacks tip height among its neighbors, and the difference between these two). A user can use the `difference_from_max_peer` value to decide what is a good threshold for them before considering the node out of sync. The endpoint returns a 500 status code if the query cannot retrieve viable data.
