Update to Go 1.12.5 testing. Remove deprecated unused and gosimple pacakges, and mask staticcheck 1006. Also, fix unconvert errors related to unnecessary type conversions and following staticcheck errors: - remove redundant return statements - use for range instead of for select - use time.Since instead of time.Now().Sub - omit comparison to bool constant - replace T.Fatal and T.Fatalf in tests with T.Error and T.Fatalf respectively because the goroutine calls T.Fatal must be called in the same goroutine as the test - fix error strings that should not be capitalized - use sort.Strings(...) instead of sort.Sort(sort.StringSlice(...)) - use he status code of Canceled instead of grpc.ErrClientConnClosing which is deprecated - use use status.Errorf instead of grpc.Errorf which is deprecated Related #10528 #10438
