Today Elasticsearch accepts, but silently ignores, port ranges in the `discovery.seed_hosts` setting: ``` discovery.seed_hosts: 10.1.2.3:9300-9400 ``` Silently ignoring part of a setting like this is trappy. With this change we reject seed host addresses of this form. Closes elastic#40786 Backport of elastic#41404
