      Description

      According to https://github.com/apache/camel/blob/master/components/camel-http4/src/main/docs/http4-component.adoc it is possible to provided a custom HttpClient with the query parameter _httpClient _.

      When I try to use parameter the route can not be created because the httpClient does not see to be looked up in the registry:
