Basic test which confirms new inputs can be created and that messages can be sent to a UDP-GELF input using `netcat`. This test requires 4GB of RAM to avoid issues due insufficient memory (please refer to `nixos/tests/elk.nix` for a detailed explanation of the issue) for elasticsearch. Also it's ensured that elasticsearch has an open HTTP port for communication when starting `graylog`. This is a workaround to ensure that all services are started in proper order, even in test environments with less power. However this shouldn't be implemented in the `nixos/graylog` module as this might be harmful when using elasticsearch clusters that require e.g. authentication and/or run on different servers.
