Kinesalite - provide name of a stream to be auto-created

[camjackson]

One of the great things about e.g. the official postgres image is that you can specify a POSTGRES_DB environment variable, and it will automatically create a database with that name. This saves you from having to have some kind of db setup script to create the database, user, etc.

It would be awesome if the kinesalite image had similar functionality. If I specify a KINESIS_STREAM or something like that, it could create that stream when initialising the container, and then I can just use it right away.
