This squelches the following warning:

warning: parser/current is loading parser/ruby24, which recognizes
warning: 2.4.4-compliant syntax, but you are running 2.4.5.
warning: please see https://github.com/whitequark/parser#compatibility-with-ruby-mri.

Even though we currently only should have one group for a cluster, we
allow the flexibility to associate to other groups in the future.

This also matches the runner <=> groups association.

- Adds Cluster#first_group, aliased to Cluster#group. For the
conceivable future, a cluster will have at most one group.

- Prevent mixing of group and project clusters. If project type
clusters, it should only have projects assigned.  Similarly with groups.

- Default cluster_type to :project_type. As it's very small table we can
set default and null: false in one release.
