Make diagnostic manager initialization processus.

It is initiliazed with by default the first CAN bus
device in the CAN bus device list from CAN bus manager.

The object is instancied at configuration_t object first
invokation and after all CAN buses has been initialized then
the diag manager is initialized too.
