title: Search RealmConfiguration by name and use it
body: <p>I am using Realm with my android project. Currently I am defining the default realm configuration in my application class as follows-</p>
  
  <pre><code> @Override
  public void onCreate(){
  super.onCreate();
  myApplication=this;
  RealmConfiguration realmConfiguration = new RealmConfiguration.Builder(this).deleteRealmIfMigrationNeeded().build();
  Realm.setDefaultConfiguration(realmConfiguration);
  Thread.setDefaultUncaughtExceptionHandler(new UnhandledExceptionHandler());
  
  }
  </code></pre>
  
  <p>In current scenario only 1 user uses a device. She logs in to the app using her credentials and uses default realm configuration.</p>
  
  <p>However with new requirements, the same android device can be used by different users and hence I need different realm configurations for each user so that each user has their own realm file right?</p>
  
  <p>If this is true then what is the best way to manage realm configurations. 
  Currently the only way to assign default configuration to realm is by using a realConfiguration instance. But how can I check if a realConfiguration exists (by name?) and then initialize Realm using that configuration?</p>
  
  <p>Thanks</p>
