When using EC2 plugin to stop (not terminate) slave instances after a certain amount of idle time, if you stop manually one of those slaves before the stop signal is sent, you can see in the logs messages like the following one:

INFO	h.p.ec2.EC2RetentionStrategy#internalCheck: Idle timeout of [XXX] after 82 idle minutes
INFO	h.plugins.ec2.EC2AbstractSlave#idleTimeout: EC2 instance idle time expired: [XXX-ID]
INFO	h.plugins.ec2.EC2AbstractSlave#stop: EC2 instance stop request sent for [XXX-ID]

The plugin keeps sending the stop signal even if the instance is already stopped.
This message fill the logs. Any way to remove it?
