A malicious user with:
* API access normally reserved for the provisioning,
cleaning, rescue networks.
* Insight about a node, such as a MAC address, or baremetal node
UUID.
* Insight into the state of the node, such as the access provided
to Compute API users, or other Bare Metal API users.
Can submit an erroneous ``heartbeat`` to the ironic-api endpoint
with a ``callback_url`` that is not of the actual intended agent.
This can potentially cause a rescue, cleaning, or deployment
operation to be derailed, or at worst commands to be sent to
to an endpoint the malicious user controls.
