Fixing org.opensearch.common.network.InetAddressesTests.testForStringIPv6WithScopeIdInput

[reta]

Signed-off-by: Andriy Redko andriy.redko@aiven.io

Description

There is a real possibility that loopback interface has no IPv6 address assigned (fe IPv6 is disabled, ...) but the test blindly assumes that loopback interface always has IPv6 address and as such, fails with java.net.UnknownHostException: no scope_id found if that is not the case.

org.opensearch.common.network.InetAddressesTests > testForStringIPv6WithScopeIdInput FAILED
