Use subscription's sockets as shared_ptr
This change is made to leverage C++ to read and write the different socket classes depending on CAN protocol used. Bug-AGL: SPEC-2386 Change-Id: I5e25e271fc82e9627f836aeb43b2af5ef25db83a Signed-off-by: Stephane Desneux <stephane.desneux@iot.bzh> Signed-off-by: Romain Forlot <romain.forlot@iot.bzh>
