…s on configure (#698)

• Create ParamListener and get parameters on configure

• Declare parameters for test_force_torque_sensor_broadcaster

Since the parameters are not declared on init anymore, they cannot be set without declaring them before

@xueying4402, all pull requests must be targeted towards the master development branch.
Once merged into master, it is possible to backport to humble, but it must be in master
to have these changes reflected into new distributions.

I don't understand your PR. There was already a backport #750. Is this new code now?

Edit: we reverted the change for a good reason #1003 and should not be necessary with #1332 any more

Hello!

I agree with @christophfroehlich. This is not needed anymore. You are supposed to declare them in the init and the get them in the configure, so you will be able to change parameters before configuring it again. You should be able to set the parameters at loading time by passing the parameters file path.

Thank you!

Please recheck the approach and get back to us.

@christophfroehlich @saikishor @olivier-stasse Thank you for the feedback. I have confirmed that the issue addressed in this PR was previously resolved and then rolled back. I apologize for any oversight on my part.
The intent behind this submission was to fix the same bug in the humble release. However, it seems this is no longer necessary.
Thank you for your patience and guidance.
