Ros-snapd: ros-snapd-support

This request is the same as the one already approved for the ros2-snap, but for the ROS (1) version.

This request has been added to the queue for review by the @reviewers team.

I think the request makes sense for the same reasons already discussed in Ros2-snapd: ros-snapd-support and snap-refresh-observe. +1 from me (#voteFor)

This is a +1(#voteFor) from me as well to allow auto-connection for the ros-snapd-support interface given the previous discussion and decision. Thanks!
