The ioredis client used by bull makes no guarantees that the `serverInfo` field be updated upon issuing an INFO command, and in fact does not appear to do so (given bull 3.13.0 and ioredis 4.16.3). While the `serverInfo` field is indeed populated after the initial connection is established, it is not updated by calling INFO as assumed with the previous logic. This results in stale data being presented by Arena. Rather than relying on this undocumented and evidently fragile behaviour, we can instead parse the result of the INFO command on our own. This also happens to step around an issue with the way that ioredis parses key-value data in handling the INFO response, where values containing the colon character are incorrectly trimmed. Given the stability and superb backwards-compatibility of Redis, this should be a highly reliable solution.

This PR fixes #218.
Rather than relying on inconsistent behaviour which ioredis no longer appears to demonstrate, the resulting data from issuing an
INFOcommand is parsed directly.As an alternative to recreating the wheel with an info parser here, we could always rely on a library such as
node-redis-infoto have things handled.
