feat: add auto_start read side setting

[Tochemey]

Feature description

This PR adds an AUTO_START setting to any readside.

• When AUTO_START is set to true, the readside will start normally or will be resumed in case it was paused to start processing events.
• When AUTO_START is set to false, the readside will start in paused mode which means it cannot process any events. To resume processing events one can perform any of the following actions:
  • use the CoS CLI tool to resume/restart the given read side (while CoS is still running)
  • stop CoS and set that feature to true and reboot CoS

The feature has been successfully QA with the various scenario
