Currently, all lab servers have local autotest setup except for devserver. When we push to prod, we are using the script under local autotest to update the servers, and using the shadow_config file to find out which service needs to be restarted. In order to use the existing script and make devserver is consistent with other servers, we need to setup local autotest in devserver too. Two benefits:
1. Do not to rewrite all the push to prod script into server lib tasks from scratch. And there is no unittest for server lib tasks
2. Devserver will have same repo checkouts with other lab servers, which makes the lab consistent
