WIP: a standalone script to check device connection status.

[130s]

Intent of PR

DO NOT MERGE. No intention to have this merged.
Opened a PR just to share even premature state, as it is use-able for temporary debugging.

What is the change

Adding a standalone Python script to add a feature to capture some device connection status.

Usage

Needs documented.

The following is very temporary usecase.

./rs_status.py

This generates a file called realsense.log on the same path where the .py file exists.

Future intent

Brush up to make it more use-able for generic usecases. Then send a PR to intel-ros/realsense upstream as well.

• Installable script.
• Configurable output file path (once installed path must be configurable).
• Handle dependency (restricted by python-usb availability)
• Integrate as roswtf plugin (similar to Add a simple roswtf plugin that checks the number of connected devices ros-drivers/openni2_camera#80).
• else?
