Disable camera info latch

[jaagut]

Is your feature request related to a problem? Please describe.

The depth_image_proc package requires zipping of the camera_info and image message, as the camera info might change for some cameras during operation (e.g. optical zoom). It, therefore, requires the camera_info message to be sent for every image.

Describe the solution you'd like

Partially implemented in bit-bots/wolfgang_robot#235 for ROS1
