* Interface that allows the servlet deployment to be modified before it is deployed.
*
* These extensions are loaded using a {@link java.util.ServiceLoader} from the deployment
* class loader, and are the first things run after the servlet context is created.
*
* There are many possible use cases for these extensions. Some obvious ones are:
*
* - Adding additional handlers
* - Adding new authentication mechanisms
* - Adding and removing servlets
