MINOR: mux-quic: Add .ctl callback function to get info about a mux connection

Other muxes implement this callback function. It was not implemented for the
QUIC mux because it was useless. It will be used to retrieve the current/max
number of stream for a quic connection. So let's added it, adding the
default support for MUX_CTL_EXIT_STATUS command.
