cli: allow node status to work on unavailable/broken clusters

Expand the `crdb_internal.gossip_liveness` and
`crdb_internal.gossip_nodes` tables to include columns needed to satisfy
the basic usage of `node status`. Specifically, added `address`,
`build`, `started_at`, `updated_at` and `replicas` columns. Changed
`node status` to use `gossip_{liveness,nodes}` instead of
`kv_node_status`. The latter table requires the range containing the
consistent node status descriptors to be available, while
`gossip_{liveness,nodes}` only retrieves info from gossip.

`node status` and `node status --decommission` will work on
unavailable/broken clusters as long as the node they are pointed to is
up. `node status {--stats,--ranges,--all}` continue to require a
reasonably healthy cluster.

Fixes cockroachdb#16489

Release note (cli change): Enhance `node status` to work on
unavailable/broken clusters.
