Add settings and configurations to the PEAK agents through the yaml file

[brunus-reberes]

• In a synchronization scenario, the sync agent should have access to the synchronizer name without additional effort, and the synchronizer should have access to the names/list of agents the he will synchronize
• Additional configurations like paths to files, and communities JIDs should be allowed to be shared among the agents through the yaml file
• If an agent needs more parameters than the ones used in the agent's init function, then the yaml should allow the configuration of those parameters and pass them to the agent
• add option to add paths to the system path
