Orion initiated connection/communication to the EOC

When connecting an EOC to an Orion platform, add an option such that the connection/communication is initiated from the Orion platform to the EOC.  This allows deployments in environments adhering to the Purdue security model to stay compliant using the security principle of "writing up, and reading down".  That way if the Orion server is in a more secure zone (based on the Purdue security model) the conversation will be initiated from the more secure zone and comply with the higher security posture.
