allow json format via zenoh, rvised test, multiple config files, deactivated autostart of zenoh bridge at cli startup

[n-mat]

Description

This PR:

• deactivates the autostart of the zenoh bridge with the adore cli -> zenoh bridge needs to be started manually or together with the secenario launch file
• adds 'config_paths' launch parameter to zenoh bridge. This feature allows to have multiple config files in different directories to configure the zenoh bridge
• adds changes for json (non-ROS) clients
• should not change behaviour for ROS clients
