Allow app to export data to this page

[davglass]

For phpinfo php modules can export data to be shown in this page.

We should look into the best way that an app or other modules can export data to be displayed here.

Examples:

• database connections
• disk status
• network status
• etc

My initial thought on this would be:

//node-info

process.on('node-info', function(data) {
    //store the data
    //needs to be a defined Object
    //maybe add a db cache here (memcache, etc)
});

//the app
process.emit('node-info', function() {
    return {
         {
             //my data 
         }
    };
});

Just a thought..

We want to expose info only when /node-info is requested yes? I'm guessing that we want to do the work of calculating the info when it's needed.

One idea is to use the sidedoor NPM module and look for a node-info door. (We'll have to define an API for this door.) This lets random modules provide details. (We could walk require.cache looking for modules with this door.) Hmmm... this doesn't work so well for modules which construct objects, especially if the object has configuration/options.
