Add URIs to connection information

[halkeye]

Some applications like to have connection strings which isn't really
possible to build with the current implementation, so take in the
cluster connection string, and replace the user information with the
user

Is there something specific preventing this from being merged?

So i used it for a bit. It mostly works but not always. I forgot what broke for me. I think the fact that its only the same db every time?

I switched to https://github.com/movetokube/postgres-operator (or my fork which adds support for do's non standard port) for managing users. It doesn't spin up new clusters though, just manages users and dbs.
