DO NOT MERGE IP connectivity metrics: introduce ConnectStatistics and DNS statistics
This patch introduces a ConnectStatistics message for collecting
Android devices connect() statistics.
It also changes DNS latency events to be grouped by (query_type,
query_return_value) to optimize space usage. For this purpose, a new
DNSLookupLatencies message is introduced and DNSLookupBatch is
deprecated. New counter fields are added for the number of queries,
and number of responses with A and AAAA records.
Test: manually taking a diff with reference ipconnectivity.proto
