Bug Description
R1.10 34
On one of the setups in the field, API Server UVE on one of the three config nodes was shown as Non-functional
Its connection to Discovery was shown as Down with reason "Heartbeat -Connection Error"
Due to this, contrail-status would report the api-server as initializing.
Sundar debugged the issue and found that once a connection to Discovery is set to Down initially, on reconnecting to the discovery, the status is not updated to Up and continues to be marked Down forever.
Workaround would be to restart API Server

(1) When Heart beat to the discovery server fails [haproxy down/not started], the discovery client library marks the Discovery connection as DOWN.
However, on successful Heart beat, the connection status is not being marked UP. Also, reset the connection status to DOWN when the response code for
HeartBeat request is not 200.
(2) Increasing the timeout for introspect connection in contrail-status to 0.5 seconds.
In swisscom setup, changing the timeout from 0.01 to 0.1 did not work. Did not see much load on the system. Changing the timeout to 0.5 to be on the safer side.
