Document the various ways of controlling a joint #1019
Description
Ignition Gazebo offers many out-of-box controllers with different features and intended use cases, for example:
It can be difficult for users to choose what to use. So it would be nice to have a high-level joint control tutorial explaining the features and usage of each of them, and why a user would choose one over the other.
Desired behavior
We should have a new tutorial in https://ignitionrobotics.org/api/gazebo/5.1/tutorials.html which summarizes all ways of controlling a joint.
Alternatives considered
Instead of documenting just joint controllers, we could document all ways of moving things, including links, models, etc. This reminds me of this great Gazebo classic tutorial: Setting Velocity on Joints and Links
Implementation suggestion
Add a tutorial here: https://github.com/ignitionrobotics/ign-gazebo/tree/ign-gazebo5/tutorials
