Add SBE timeout handling

Add an Error instance to detect SBE timeouts in the driver.
Refactor the PLDM code to handle another requeset type (the HRESET) and
another type of sensor event (success or failure of the HRESET).
Handle the timeout and the PLDM event state change in the Manager by
changing the SBE state and requesting an SBE dump if necessary.
