If we need to stop swss during fast-reboot procedure on the boot up path,
it means that something went wrong, like syncd/orchagent crashed already,
we are stopping and restarting swss/syncd to re-initialize. In this case,
we should proceed as if it is a cold reboot.

Add the same mechanism I developed for the SwSS service in #2845 to the syncd service. However, in order to cause the SwSS service to also exit and restart in this situation, I developed a docker-wait-any program which the SwSS service uses to wait for either the swss or syncd containers to exit.
radv should be left alone during warm restart of swss. Otherwise it will
announce departure and cause hosts to lose default gateway.

* [service dependent] describe non-warm-reboot dependency outside systemctl
When dependency was described with systemctl, it will kick in all the time,
including under warm reboot/restart scenarios. This is not what we always
want. For components that are capable of warm reboot/start, they need to
describe dependency in service files.

* [service] teamd service should not require swss service
Adding require swss will cause teamd to be killed by systemctl when swss
stops. This is not what we want in warm reboot.

* refactoring code
* rename functions to match other functions in the file
start() is called by service startPre method, which is blocking. Starting
syncd service here is causing deadlock.
attach() is called by service start method, which is non-blocking.

* [services] Ensure swss and syncd services start before dependent services
* Add 'attach' functions to scripts which get installed to /usr/local/bin so that services only reference the one script each
* Add 'After=swss.service' to syncd.service
need to flush asic db in swss.sh instead of syncd.sh
orchagent might already started in swss.sh and put commands
into asic db before asic db is flushed in syncd.sh. This
causes race condition such as INIT_VIEW not passing to syncd.

Clear WARM_RESTART table could cause component level warm restart to
fail due to missing WARM_RESTART state.

This script shall not flush all the entries in the state database
when it starts up, since there are entries maintained and written
by other processes outside this docker.
The issue we noticed was that the portchannel states are cleaned
up after teamsyncd writes the entries into the database, which
causes the IPs failed to be configured because intfmgrd considers
the portchannels are not ready yet.

* 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.
