Okay I chatted with @pwendell , and the decision in as follows.
1. Name = StreamInputInfo,
2. It will have the field info: Map[String, Object]. Rather than a string,
its most future-proof is to use a Map[String, Object], as we may want to not
just strings but actual objects. For example, for files, one of the keys in the
map be "files" and the value is a list of files.
3. Deprecate streamIdToNumRecords and introduce streamIdToInputInfo:
Map[Int, StreamInputInfo]
4. object StreamInputInfo can have well known key names like for number of
records, etc. They are used to store the corresponding data in the map.
