Add nextcloud-exporter to official Nextcloud AIO containers.

[apoorv569]

I recently asked for getting some metrics from my Nextcloud instance and export it to something like prometheus or influxdb, and they recommended me this project.

So I was wondering if you would be interested in adding this container to the official community containers for AIO.

You can find the conversation here. nextcloud/all-in-one#5219

I'm currently not at home, but I'll have a look at this issue once I'm back.

I have had a cursory look at what AIO is and what's needed to get the exporter included. I think I'll have to play around with this a bit first to get a feel for it, but overall this doesn't sound like a bad idea, as it looks as if this is just configuration which reuses the already existing image and there's no constant maintenance associated with it.
Probably will not get this done today, but we'll see ...

Sorry, I do realize that it has been another month. This is not forgotten, just had different things to do.
