MINOR: quic: refactor app-ops initialization

Browse Source 
Add a new function in mux-quic to install app-ops. For now this
functions is called during the ALPN negotiation of the QUIC handshake.

This change will be useful when the connection accept queue will be
implemented. It will be thus required to delay the app-ops
initialization because the mux won't be allocated anymore during the
QUIC handshake.
