Add a tool to the openshift-mcp-server which performs equivalent of PrintBasicClusterState (i.e. https://github.com/openshift/oc/blob/0c09391d89b24f45dc606eee749e67d9b52c9f70/pkg/cli/admin/mustgather/summary.go#L17-L52) as printed towards the end of every `oc adm must-gather` cli execution.

Acceptance criteria: tooling in openshift-mcp-server's openshift toolset with the basic cluster state summary details.
