Change Description
This commit tightens up parsing of RabbitMQ-related command line arguments (it simplifies the code, improves readability, and adds a comment and a unit test).
Change Type
On Linux, specifying
--stream-rabbits-exchangecrashes rodeos with SEGFAULT. On macOS, it was observed that the log contained "RabbitMQ Connected Successfully! Exchange ΠΏοΏ½οΏ½". Apparently, there's a read access of deleted memory in the onSuccess lambda. It can no longer be reproduced after this commit. If this commit doesn't fix the Linux bus error, I'll investigate it separately.Consensus Changes

A comment to
parse_rabbitmq_addressinrabbitmq.hppexpands a little bit on the format of the argument of the rodeos options--stream-rabbitsand--stream-rabbits-exchange.
