CLI: List existing databases

[xNul]

I think it would be useful to have a command which lists all existing databases since a database name is needed for most of the CLI's commands. Maybe spacetime list where adding an identity is optional?

I would like this as well. It seems spacetime list definitely seems like a great spot for this. With a change to the command to include also fetching the DNS of the database via the /database/reverse_dns/:address endpoint, I was able to get an output like this:

I think this would be a nice QoL change that I would appreciate.

This is a great idea! CLI needs some work generally I think

@xNul I made a change I've built locally that I like to use to get db names easily if you are looking to have that for now until the StDB team makes the addition. (Source in linked PR above)
