Improve server insights

It takes a bit too much time for the server insights to give new data. My server gains around 500 members every week but I need to wait 2 weeks to get meaningful stats on how the server is doing in terms of messages sent, voice minutes, member retention and so on... It would be better if data came in faster.

The amount of data it shows is not much as well, it would be nicer if it had shown the top active users in terms of messages sent, voice minutes etc..

Kind of a shame that a few bots are able to do these things better than the Discord's server insights.
