sink reads resources from stdin and writes them to a local directory.
Resources must be in one of the following input formats:

1. Multi object YAML where resources are separated by ---.

2. KRM Function Specification wire format where resources are wrapped in an
   object of kind ResourceList.

sink is useful for chaining functions using Unix pipe. For more details, refer
to [Chaining functions]({{% relref "/book/04-using-functions#chaining-functions-using-the-unix-pipe" %}}).
