Set MaxStale default to 10 years and add a stale counter ( #2481 )
...
Default MaxStale to 10 years and add a counter at `consul.dns.stale_queries` that tracks when an agent serves a query that's stale by at least 5 seconds. Previously, MaxStale defaulted to 5 seconds and DNS would become unavailable after a short period of time with no leader. This new default allows DNS requests to still be served in the event of a long outage.
Fixes #2460 .

Corrects two issues with DNS prepared query failover
...
When DNS prepared query fails over to another datacenter and the datacenter
returns some nodes, the DNS result does not translate WAN addresses even when
translation is enabled for SRV and A queries, and returns the wrong datacenter
(the one that failed over) for SRV queries.
