Callback used to initialize the agent and model for the reinforcement learning and put it in the list.

predict mode it uses the phonebooks to create an input vector to the reinforcement learning model. This
input vector consists of all possible nodes that the satellite could send or receive data from. The callbacks
then loads the trained model and weights, and creates a new agent and appends it to the agent list so that
other callbacks can access the agent.
