class CiscoCfgAgent(manager.Manager):
"""Cisco Cfg Agent.
This class defines a generic configuration agent for cisco devices which
implement network services in the cloud backend. It is based on the
(reference) l3-agent, but has been enhanced to support multiple services
in addition to routing.
The agent acts like as a container for services and does not do any
service specific processing or configuration itself.
All service specific processing is delegated to service helpers which
the agent loads. Thus routing specific updates are processed by the
routing service helper, firewall by firewall helper etc.
A further layer of abstraction is implemented by using device drivers for
encapsulating all configuration operations of a service on a device.
Device drivers are specific to a particular device/service VM eg: CSR1kv.
The main entry points in this class are the `process_services()` and
`_backlog_task()` .

the config agent has received a notification from the plugin that
some hosting devices are going to be removed. The payload contains
the details of the hosting devices and the associated neutron
