* [swss.sh] refactor ssh service script code
- Move checks and waits to helper functions.
- Remove early returns from code stream
Signed-off-by: Ying Xie <ying.xie@microsoft.com>
* [swss.sh] Add debug log for service state changes
Signed-off-by: Ying Xie <ying.xie@microsoft.com>
* [syncd] Separate out syncd service from swss service
Still make them start/stop/restart synchronously so existing scripts
continue working.
Signed-off-by: Ying Xie <ying.xie@microsoft.com>
* Remove extra 'After' in swss service and remove syncd docker warm boot code
Syncd warm boot needs more thinking, we can put it back once the work
flow has been defined and ready for coding/testing.
* [syncd] syncd start/stop/restart shouldn't affect swss state
Semi-detach syncd service state change from swss:
- swss state change still chase syncd service to follow except warm boot
- syncd state change will only affect itself.
