MINOR: quic: display infos about various encryption level on "show quic"

Browse Source 
Complete "show quic" handler by displaying various information related
to each encryption level and packet number space. Most notably, ack
ranges and bytes in flight are present to help debug retransmission
issues.

This should be backported up to 2.7.
