bullet-featherstone: Enforce joint velocity and effort limits for velocity control commands

[iche033]

🎉 New feature

Closes #

Summary

Updated SetJointVelocityCommand to enforce joint limits by

• manually clamping velocity cmds
• passing impulse to btMultiBodyJointMotor instead of effort

Added the following features:

• SetJointPositionLimitsFeature
• SetJointVelocityLimitsFeature
• SetJointEffortLimitsFeature

Test it

Enabled tests in joint_features related to testing joint limits using velocity control. There are still issues with force control so those tests remain disabled in bullet-featherstone

Note I added collisions to the simple_joint_test in test.world (used by various joint limit tests) because bullet-featherstone requires a link to have collisions otherwise the joints do not move.

Here's a joint_limits.sdf world that consists of a simple model with JointPositionController

Before: joint limits not enforced so joint rotates at a high speed

After: joint limits enforced
