/**
* Service-provider interface for creating container instances.
*
* If supported by the provider, a container instance of the requested Java type
* will be created.
*
* The created container is responsible for listening on a communication chanel
* for new client requests, dispatching these requests to the registered
* {@link ApplicationHandler Jersey application handler} using the handler's
* {@link ApplicationHandler#apply(org.glassfish.jersey.server.ContainerRequest)}
* apply(requestContext)} method and sending the responses provided by the
* application back to the client.
*
* A provider shall support a one-to-one mapping between a type that is not of
* the type Object. A provider may support
* more than one one-to-one mapping or a mapping of sub-types of a type
* (that is not of the type Object). A provider shall not conflict with other
* providers.
*
* An implementation (a service-provider) identifies itself by registering a proper
* HK2 {@code ContainterProvider} contract binding in a custom HK2 binder configured
* in the Jersey application handler.
* Alternatively, the implementation can identify itself by placing a provider-configuration
* file (if not already present), {@code org.glassfish.jersey.server.spi.ContainerProvider}
* in the resource directory META-INF/services, and adding the fully
* qualified service-provider-class of the implementation in the file.
