--capabilities option for Linux apps does nothing

[bzbarsky-apple]

Problem

In ChipLinuxAppInit we parse command line args like so:

    err = ParseArguments(argc, argv, customOptions);

which for --capabilities will do:

    case kDeviceOption_Capabilities:
        LinuxDeviceOptions::GetInstance().payload.rendezvousInformation.SetRaw(static_cast<uint8_t>(atoi(aValue)));
        break;

Then back in ChipLinuxAppInit we do:

    err = GetPayloadContents(LinuxDeviceOptions::GetInstance().payload, rendezvousFlags);

where rendezvousFlags is based on some build-time defines, and that does:

    aPayload.rendezvousInformation = aRendezvousFlags;

which overrides the value that came from the command line.

Proposed Solution

What is the actual intended behavior of this command-line option? Is it meant to change the behavior of the application, or just the pairing codes that get printed?
