Subject: [PATCH] CLOUDSTACK-3409: Do not clean up security group rules for
 Instances in the "paused" state.

When 'security_group.py cleanup_rules' is called by the KVM Agent it will clean up all Instances
not in the "running" state according to libvirt.

However, when a snapshot is created of a Instance it will go to the "paused" state while the snapshot
is created.

This leads to Security Rules being removed when a Instance is being snapshotted and the cleanup process
is initiated.
