Topics flags

This module provides 2 helpers to parse collections of topics.

1. List of topics, such as:

statusd -topic.register=whisper -topic.register=les

2. List of topics with limits per topic. Main use case is to define per-protocol peer limits:

statusd -topic.search=whisper=7,9 -topic.search=mailserver=1,1 -topic.search=les=1,2
