Remarks
Sets whether Cronet should use stale cached DNS records to pre-establish connections.
If enabled, Cronet will optimistically pre-establish connections to servers that matched the hostname at some point in the past and were cached but the cache entry expired. Such connections won't be used further until a new DNS lookup confirms the cached record was up to date.
To use cached DNS records straight away, use setStaleDns(int) and StaleDnsOptions configuration options.
This option may not be available for all networking protocols.
