JSON support for consumer data

[jim12321]

Hello. So just want to say that we love this software. Very useful.

We just wanted to have consumer data in JSON.

When you make a call to /topic/

You get that in JSON, but it does not include the consumer group data table that you see in http:

Consumers

Group ID	Combined Lag
****	155632

Could this data be added to the JSON request for topic/?

Also could /consumer/ endpoint support JSON too. When sending Accept application/json it still sends HTML and not JSON.

Thanks

Currently a bit tied up with work. There are a bunch of controllers that do this sort of thing already, so should mostly be a copy-paste job. Would you consider submitting a PR?

Would love to help, but I am only a lowly Python programmer. Not sure you want me to try and submit a PR. ;)

@jim12321 The modest coders are the best, in my experience ;)
