I made VIS_MANAGER who manages all guardians of the VIS suspensions when earthquake hit.

Description

• First, guradstate of the all suspensions are "ALIGNED" or "OBSERVATION".  So, the nominal state of VIS_MANAGER is "ALL_ALIGNED" which is a guradstate to request each suspensions to go "ALIGNED" or "OBSERVATION".
• When earthquake hit in KAGRA mine, which means three seismometer detect large signal at the same time, VIS_MANAGER move to "EARTHQUAKE" state and immediately request all suspension to go to "PAY_LOCALDAMPED" for safety.
• After ground motion calm down, VIS_MANAGER goes to "IDLING" state. In this state, VIS_MANAGER do nothing. But, because of the nominal state is "ALL_ALIGNED", VIS_MANAGER move to this state again.
• Finally, all suspensions come back to "ALIGNED" or "OBSERVATION" state.

Now, I engaged this manager guardian.

If you find some bug, please report me.
