Plugin does not load without core jar deployed

[Lennart Koopmann]

A reporter plugin is supposed to load without the metrics-reporter-core-x.x.x.jar in the plugins/ folder but it does not. This is 100% reproducible on my setup and two customers had the same issue but not on @joschi's setup.

lennart@graylog-srv01:/usr/share/graylog-server/plugin$ unzip -l metrics-reporter-datadog-1.4.0.jar | grep org/graylog/plugins/metrics/core

@lennartkoopmann Since this couldn't be reproduced, I'm closing this issue.
