Description

In http://www.rudder-project.org/redmine/issues/2607 we implemented a mechanism to check if the cf_lock.db was preventing the agent from running, but we have overlooked the server part.
We should implement the same kind of mecanism for the server

I do not understand, this modification has been done on the failsafe and the common policy, this should work on the server too...

Matthieu, this PR is necessary for Rudder 2.6, but does not address the issue in this ticket.

To explain a bit better: the promise you changed looks at the last_successful_inputs_update file and if it's too old, kills cf_lock.[tc]db. However, this file is only generated if "!root_server", see https://github.com/Kegeruneku/rudder-techniques/blob/fddad39aad3c4a87f3e68da6ac3382717aa5315f/techniques/system/common/1.0/update.st#L108. That is the problem here.

I think a simple fix is to adapt the "touch" on the last_successful_inputs_update file, and always do it if we are the root_server. That way, if cf-agent does block, it will not get touched, and we'll reset the cf_lock DB file, but not otherwise. I will create a pull request for this.

Can you create another ticket for your original pull request?
