Subject: [PATCH 13/54] Use tf2::BufferCoreInterface

Using this abstract interface enables use of the interactive marker client with other buffer implementations.

Also, switched to using shared pointers to avoid potential dangling reference.

Subject: [PATCH 14/54] Replace 'init' topic with a ROS service

It seems more intuitive for clients to call a service to get the latest state for interactive
markers, versus subscribing to a latched topic and waiting for the server to publish.

From 7eaeeab4c170e84b90704cd12cd35b33d2ac2760 Mon Sep 17 00:00:00 2001
From: Jacob Perron <jacob@openrobotics.org>
Date: Mon, 29 Jul 2019 19:00:00 -0700
Subject: [PATCH 21/54] Major refactor

Merge SingleClient logic into InteractiveMarkerClient.
Now it is assumed that there is maximum one server per client.
This helps simplify the implementation.
