Currently, users have to deny-list an ever-growing and changing set of fields. This ticket allows users to allow-list the fields they are interested in.

Many fields are included by default in serverStatus. Filtering out all default fields on the server-side is cumbersome for clients at this point. Version to version changes in the default set introduce more complexity to server-side filtering.

Implement a {none: 1} that will filter out all default fields by default. After this flag, fields can be explicitly included.
