Accepts the certificate from a heartbeat and stores its path in driver_internal_info for further usage by the agent client (or any 3rd party deploy implementations). Similarly to agent_url, the certificate is protected from further changes (unless the local copy does not exist) and is removed on reboot or tear down (unless fast-tracking).
