David Turner 421f58e172 Remove discovery-file plugin (#33257) ... In #33241 we moved the file-based discovery functionality to core Elasticsearch, but preserved the `discovery-file` plugin, and support for the existing location of the `unicast_hosts.txt` file, for BWC reasons. This commit completes the removal of this plugin.		2018-09-18 12:01:16 +01:00
