0.0.12

• fix issue where function executions were always crashing under normal circumstances when connection was severed from the server side.
• set the number of function retries from default of 2 to 0 in order to prevent unexpected function re-executions (like for issue above which was resulting in more function executions than expected).
• close connections and don't rely on the crashing of Lambda sandbox to do this.
• pick a dynamic listening port for socks proxy on Lambda side in order to avoid port conflicts.
• add a UUID to Lambda payload for tracing function executions
