ipcpd: normal: Refactor application entities and add neighbors struct

This refactors the different Application Entities of the normal
IPCP. They all listen to and use the connection manager to establish
new application connections.

This commit also adds a neighbors struct to the normal IPCP. It
contains neighbor structs that contain application
connection. Notifiers can be registered in case a neighbor changes
(added, removed, QoS changed).

The flow manager has an instance of this neighbors struct and listens
to these events to update its flow set. The routing component also
listens to these events so that it can update the FSDB if needed. The
flow manager now also creates the PFF instances and the routing
instances per QoS cube.

The RIB manager also uses this an instance of the neighbors struct and
listens to neighbor events as well.
