[jsk_tools] Add node to publish diagnostics based on topic and node status

[708yamaguchi]

This node checks topic and node status and publishes /diagnostics topic.

I refine jsk-ros-pkg/jsk_robot#1460 by using sanity_lib.py.
https://github.com/jsk-ros-pkg/jsk_common/blob/a3d26ac5243c108cec25d4108d93b3f0fd57c503/jsk_tools/src/jsk_tools/sanity_lib.py

$ rostopic echo /diagnostics
header: 
  seq: 1
  stamp: 
    secs: 1652277254
    nsecs: 167789936
  frame_id: ''
status: 
  - 
    level: 0
    name: "/respeaker_node"
    message: "Node is alive"
    hardware_id: ''
    values: []
  - 
    level: 0
    name: "/kinect_head/kinect_head_nodelet_manager"
    message: "Node is alive"
    hardware_id: ''
    values: []

header: 
  seq: 2
  stamp: 
    secs: 1652277254
    nsecs: 601408004
  frame_id: ''
status: 
  - 
    level: 0
    name: "/kinect_head/rgb/image_raw"
    message: "Topic is published"
    hardware_id: ''
    values: []
  - 
    level: 0
    name: "/tf"
    message: "Topic is published"
    hardware_id: ''
    values: []

In the future, I think robot speaks /diagnostics topic with this script.

This looks good!
Could you add a test and sample like https://github.com/jsk-ros-pkg/jsk_common/pull/1711/files

[708yamaguchi]

Thank you for your review.

I add sample

roslaunch jsk_tools sample_sanity_diagnostics.launch

and test

rostest jsk_tools test_sanity_diagnostics.test 

Result:

Sorry for force-push.
I summerize commits 23 -> 6.
