Description

AddressUtil#getLocalHostExactAddress might slow the query because of multiple local ip acquisitions in org.springframework.cloud.commons.util.InetUtils#findFirstNonLoopbackHostInfo.

Fix Design

Add cache of LOCAL_IP_ADDRESS. Thus, the cache is updated when calling AddressUtil#getLocalHostExactAddress at the first time, then the cache can be used afterwards.
