> Bootstrap:
> * New config parameter num_tokens which is used iff initial_token is not set.
> * Both initial_token and replace_token will allow a comma-separated list of tokens so multiple tokens can be configured explicitly if required.
> * Bootstrapper.getBalancedToken will be deprecated and used only in the case that num_tokens == 1. Instead, if initial token is not specified, num_tokens tokens will be randomly chosen.
> * The existing logic can be used to calculate the new ranges which must be streamed.
> Decommission:
> * The existing logic can be used with some minor modifications to account for multiple tokens per host
> _Edit0: appended patch information._
> _Edit1: added 03_group_stream_out_ranges patch._
