ROS2 action client in Roslibjs

[ikwilnaarhuisman]

hi @EzraBrooks, some time ago I was running into performance issues when teleoperating through the roslibjs towards the rosbridge. Using an action I kept sending goals per 100ms towards the rosbridge which causes it to spawn multiple action clients which causes significant CPU spikes.

For ROS1 roslibjs has ActionClient in here, but this obviously doesn't work for ROS2. Is there a way to make an actionClient with roslibjs or does the rosbridge protocol prohibit that?
