added lifecycle node support, handling of acquisition erros

[berndpfrommer]

This PR

• adds support for lifecycle nodes for distros where the image transport supports this
  (version must be >= 6.4.0). At the moment, this is only ROS Rolling.
• improves handling of camera acquisition errors. The driver will try to restart acquisition automatically. However, if the camera lost power and rebooted, the driver will not automatically re-apply any of the camera parameter settings.

Tested with rolling, and it seems to be working well. Thanks for making the changes. @berndpfrommer

You mentioned it is only working on Rolling. What is still open or would it take to have this working on Jazzy? Or has it simple not been tested on this Distro?

The driver is now more robust to acquisition errors on all distros. It should automatically reconnect to the camera. Tested on Rolling and Humble.
However, because the Jazzy (and I believe Kilted) image transport does not support lifecycle nodes, the lifecycle feature is only available on Rolling.
