Description

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.

Note: These are branches managed with TopGit. If you are applying the patch output manually, you will either need to filter the TopGit metadata files (i.e. wget -O - <url> | filterdiff -x*.topdeps -x*.topmsg | patch -p1), or remove them afterward (rm .topmsg .topdeps).
