svlogd adds hostname and process name when log shipper is enabled
```json sidekiq-besteffort-02-sv-gprd sidekiq-cluster: {"severity":"INFO","time":"2018-04-24T17:36:23.089Z","class":"Geo::ProjectSyncWorker","args":[4596006,"2018-04-24 17:36:22 +0000"],"retry":3,"queue":"geo:geo_project_sync","queue_namespace":"geo","dead":false,"jid":"d6d6379863a504a635351728","created_at":"2018-04-24T17:36:22.301Z","enqueued_at":"2018-04-24T17:36:22.302Z","pid":55331,"message":"Geo::ProjectSyncWorker JID-d6d6379863a504a635351728: done: 0.978 sec","job_status":"done","duration":0.978,"completed_at":"2018-04-24T17:36:23.089Z"} ``` I thought leaving `svlogd` blank with parameters would omit the hostname and process name, but it looks like this is enabled when UDP log shipping is enabled: https://gitlab.com/gitlab-org/omnibus-gitlab/blob/9eded163c756136cbbd17148e34b6cbdd17eba15/files/gitlab-cookbooks/gitlab/libraries/logging.rb#L66 @ilyaf Can we get the hostname from the log shipper, or is this a field that should be added by the logger itself?
