             Summary: Enable label and environment decorators (hooks) to remove label and environment entries
                 Key: MESOS-2351
                 URL: https://issues.apache.org/jira/browse/MESOS-2351
             Project: Mesos
          Issue Type: Task
            Reporter: Niklas Quarfot Nielsen


We need to change the semantics of decorators to be able to not only add labels and environment variables, but also remove them.

The change is fairly small. The hook manager (and call site) use CopyFrom instead of MergeFrom and hook implementors pass on the labels and environment from task and executor commands respectively.

In the future, we can tag labels such that only labels belonging to a hook type (across master and slave) can be inspected and changed. For now, the active hooks are selected by the operator and there be trusted.
