Mine-backed pillars (node_data, elasticsearch:nodes, redis:nodes,
logstash:nodes, hypervisor:nodes) include a node only if it returned an
IP from the mine, and the configs they build are rebuilt fresh every
highstate. After a manager reboot with a flushed mine, the first boot
highstate could run before an up node re-reported network.ip_addrs,
dropping it from e.g. so-elasticsearch ExtraHosts and forcing a
container recreate.
After the initial broad mine.update, poll until every currently-up
minion actually has network.ip_addrs in the mine, re-pushing mine.update
to stragglers, before releasing the boot highstate. Shares the existing
MINE_UPDATE_MAX_WAIT backstop so a slow/down node never blocks boot, and
still logs the rendered node_data for inspection.
