Gateway as single point of entry

• The gateway as single point of entry, listens for HTTP POST requests under collibra.connect.gateway on port 8081.
  The URL and port values can be changed by modifying the gateway.xml file in the gateway project (under src/main/app).
• When the gateway receives a message, it starts the integration process defined by the flowId parameter of the call.
• See Triggering an integration for an example of starting an integration by using the gateway.
