Add tx_osnr in spectral information

Browse Source 
This change enables to use a different tx_osnr per carrier.

If tx_osnr is defined via spectrum then use it to define a tx_osnr per
carrier in si else use the tx_osnr of request to set tx_osnr of si.

Then, the propagate function for requests is changed to update OSNR with
tx_OSNR per carrier defined in si.

TODO: The tx_osnr defined in spectrum is not yet taken into account for
the propagate_and_optimize function, because the loop that optimizes
the choice for the mode only loops on baudrate.
