ElasticContainer: Bump V7_0 test server to 7.0.0-beta1

As listed in the "Breaking changes" section of the release notes [1],
index creation requests are rejected when the include_type_name
parameter is not set to "true". This is a new parameter introduced
in 7.0.0, so we set it conditionally only for that version.
