Health check frozen client

[choihocheol]

Now Client Health feature can support only warning for can be expiration client. But it need to check Frozen or Expired client too.

Checking frozen or expired client feature could be implementing in the step of Initialization by checking difference with prev client.

OR

We can implement this feature like compare prev client's status and current queried client's status and then if those value aren't same then we can assume that client has problem. And we can input this features code before when warnExpiration of client health check.
