Update git submodules

* Update docs/submodules/dovetail from branch 'master'
  - Add process info to pod.yaml to specify the info of a special process
    
    1. Many HA test cases try to kill special processes with their name.
    2. Then they check corresponding openstack services and
       the status of processes' recovery.
    3. For different SUTs, the names of the processes and the hosts' names
       may be different.
    4. So there is a requirement for Dovetail tool to provide one way to
       allow users to specify all the infos about process name and its host name.
    5. All process infos can be added into file DOVETAIL_HOME/user_config/pod.yaml
    6. The infos include 'attack_process' and 'attack_host' for each HA test cases.
    7. If not given in this file, will use Yardtsick default values.
