Manage prefix on CAN and OBD2 prefix. Searching signals

is made on generic_name (without prefix) and returned
vector of string is filled with name with prefix. Then
you can process on them based upon their name differently.

OBD2 signals will generated recurring request on diagnostic
manager and decoding will not be handled the same way too.
