New slave server always listed as Database server
When a new slave server is added to an ISPConfig master, the slave server is always listed as Database server.
The installer should ask whether the new server will host databases and only enlist it as a database server in case of a positive answer. Nowadays it is more common to have a centralised DB cluster instead of running a separate DB on each web host.
ISPConfig version: 3.1.12
See the correct behaviour above.
