request: in the event of failure, try other IPs (#6761) (#6813)
* request: in the event of failure, try other IPs (#6761)

In the case where a name has multiple A/AAAA records, we should
try subsequent records instead of immediately failing when we have a
failure on the first IP address.

This significantly improves delivery success when there are network
connectivity problems affecting only IPv4 or IPv6.

* fix method call style

* request_spec: adjust test case to use Addrinfo

* request: Request/open: move private addr check to within begin/rescue

* request_spec: add case to test failover, fix exception check

* Double Addrinfo.foreach so that it correctly yields instances
