Description

One possible deployment in production is to use something like a lvs in front of all the region servers to act as a LB, so client just need to connect to the lvs IP instead of go to the region server directly to get registry information.

For this scenario we do not need to refresh the endpoints any more.

The simplest way is to set the refresh interval to -1.
