CDash 3.4.0-rc1 is ready for testing

The highlight of this feature is the introduction of a new GraphQL API. Users can now use the GraphQL API to make their own custom queries. The API currently exposes basic project, build, site, and user information, and will be expanded in future releases.

Other notable features in this release include a new RHEL-based Docker image, database performance improvements, and several new configuration options.
