[k8s] Support configurable health polling interval

Browse Source 
The default 10 seconds health polling interval is too frequent for most of
the cases. Now it has been changed to 60s. A new config
`health_polling_interval` is added to make the interval configurable.
Cloud admin can totally disable the health polling by set a negative value
for the config.
