Enabling sensor re-connection in “ouster-ros” driver

[Samahu]

Starting with version 0.12.6 for ROS1 and version 0.12.7 for the ROS2 branch the ouster-ros driver supports automatic sensor re-connection, which allows users to:

• start up the driver before booting up the sensor
• recover connection to the sensor after connection was dropped (wire disconnected)
• recover connection to the sensor after sensor power cycle
  ℹ️ In case this case the driver will reset configuration to persisted config

To enable this feature set the attempt_reconnect ros launch parameter to true (disabled by default). To have control some control over the frequency of attempts users can make uses of the two additional params:

• dormant_period_between_reconnects: time to wait between reconnect attempts, default is 1.0 second
• max_failed_reconnect_attempts: maximum reconnect attempts, default is 2147483647
