when "test quota on write" fails, it should notify pod owner

In catching up on a lot of discussion and updates, it seems that when the "test quota on write" fails it results in a notification to the attempting writer -- so if @kjetilk tries to write to @RubenVerborgh's INBOX and that write would exhaust quota, @kjetilk gets notified -- but @RubenVerborgh does not.

This is troublesome, as @kjetilk's best (and possibly only) way to inform @RubenVerborgh of this problem is via his inbox ... which is full. I think that this is a place where NSS might use @RubenVerborgh's email address to send such a notification without consuming further NSS-quota.

Comece localizando a implementação em Node.js da falha "test quota on write" e o caminho de notificação; em seguida, leia a discussão da issue 918 vinculada para obter contexto. O trabalho estará concluído quando o proprietário do pod for notificado sobre a falha de quota sem consumir quota adicional, enquanto o comportamento existente de notificação do writer continuar compreendido e coberto.
