feat(deltacast): wire source_config.port/board into capture start

Browse source 
Parse the recorder's SOURCE_CONFIG JSON in the bootstrap and pass the deltacast
capture channel (`port`) and optional `board` into captureManager.start(), so a
recorder can select which of the board's 8 channels to capture.
