Release 0.7.0 with quic

I am seeing the following in the spegel logs

Should I be concerned about this? UDP Buffer Sizes

[phillebaba]

This is not something that affects functionality. It seems that the default buffer size in most kernel configurations are too small for QUICs liking. QUIC is only used by the DHT to send messages to each other, which is not that much data. Here is a similar issue about the buffer size setting in Kubernetes environments.
quic-go/quic-go#3418

It is possible to change these settings in AKS and EKS clusters which should see some performance improvements. To avoid more of these issues it may be for the better to just disable this warning log all together.
