REST client is not released with the right groupId

[dadoonet]

Apparently we published the REST Client on maven central at https://repo1.maven.org/maven2/org/elasticsearch/rest/5.0.0-alpha4/

Which means that the artifact coordinates are org.elasticsearch:rest:5.0.0-alpha4.
But it should be org.elasticsearch.client:rest:5.0.0-alpha4.

Also reported at https://discuss.elastic.co/t/restclient-in-5-0-0-alpha4/54509

This is fixed in our gradle configuration, also the artifacts for 5.0.0-alpha4 were added in the proper locations and the groupId was updated in their corresponding poms.
