MINOR: quic: display CIDs and state in "show quic"

Browse Source 
Complete "show quic" handler. Source and destination CIDs are printed
for every connection. This is complete by a state info to reflect if
handshake is completed and if a CONNECTION_CLOSE has been emitted or
received and the allocation status of the attached MUX. Finally the idle
timer expiration is also printed.

This should be backported up to 2.7.
