Output destination can be dynamically determined from the task

[osdakira]

I want different tasks to output to different logs. Different tasks should output to different logs. Currently, we have to write :output for each task, which is not DRY. Since :output can be written dynamically, we can change the output destination dynamically by passing tasks to it.

However, since lambda requires an argument, changing it will break the existing code. On the other hand, proc works without arguments, so we can use tasks as arguments only for proc to maintain backward compatibility.
