Update config variable dynamically thru app.set

[swina]

Steps to reproduce

Using nedb as local data I'm trying to switch between 2 different folders using app.set ( 'nedb' , new_path ) thru a hook.

...
    //change nedb path
    context.app.set ( 'nedb' , path.resolve ( data_folder ) )
   //reconfigure services
   const services = require ( '../services' )
   context.app.configure ( services )
   //checking if current data folder is correct
   console.log ( context.app.get('nedb') )
...  

Expected behavior

Any service after the data folder update thru app.set should use the database in the updated folder

Actual behavior

After set a new path for nedb any query still refers to the nedb path variable defined in the default.json

This is currently not possible. The database model is initialized on application startup. The upcoming v5 will allow passing params.adapter.Model where you can set the model you would like to use for the request.
