Remove getEmbeddedServletContainers()
Remove the mutable getEmbeddedServletContainers() Map from EmbeddedWebApplicationContext and instead use the `namespace` to distinguish the management container. The ServerPortInfoApplicationContextInitializer class replaces the previous TestExecutionListener to exposes port properties (by listening for EmbeddedServletContainerInitializedEvents).pull/718/head
