FM_DELETE_INT_CC appears to be redundant with FM_DELETE_CC

[skliper]

The doxygen comment for FM_DELETE_INT_CC states: "This is a special version of the #FM_DELETE_CC command for use when the command is sent by another application, rather than from the ground. This version of the command will not generate a success event, nor will the command increment the command success counter. The intent is to avoid confusion resulting from telemetry representing the results of delete commands sent by other applications and those sent from the ground."

However, this does not appear to be the case. Both FM_DELETE_INT_CC and FM_DELETE_CC call the same functions. It appears that FM_DELETE_INT_CC does increment the command success counter, but does not send an event message from the child task.

I think that the need for FM_DELETE_INT_CC needs to be reevaluated and if it is needed, it should be updated to match its description.
