How to set Goal Threshold for JointTrajectoryAction

[riv-dpowell]

We're trying to set the goal threshold for the JointTrajectoryAction.

motoman_driver/src/industrial_robot_client/joint_trajectory_action.cpp

We've tried setting the param /<node_namespace>/constraints/goal_threshold but this isn't picked up by the node. We've confirmed it's not picked up by sending a goal with a tolerance and recieving the message:

Ignoring goal tolerance in action, using paramater tolerance of 0.01 instead

When we've set the tolerance to 1e-5.

We've successully set the topic_list with the param /<node_namespace>/topic_list and this is picked up by the node. Is there something strange with private node namespaces going on?
