Is your feature request related to a problem? Please describe.

As bot owners, we would like information about the bots usage and development in order to influence future features, and to share with partners.

Requirements

Create a command "k!insights" to give the following information

1. Number of servers the bot is in
2. Sum of number of members in all of the servers

Create a command "k!servers" to give a list of all servers the bot is in

3. list all servers the bot is in (make sure it can handle splitting into 2k character messages if it goes over that number)
4. list all servers with a given string within (e.g. "k!servers uni" would give servers with the word uni in them)

Top.gg integration

5. Update top.gg with server count (https://docs.top.gg/api/bot/#post-stats)
