test: Add single-node test configurations to CI pipeline

* Add three new test configurations for single-node testing:
  - ic-singlenode_regress
  - ic-singlenode_isolation
  - ic-singlenode_isolation2
* Update build workflow to support tests with configurable number of
  primary-mirror pairs
* Add new test configurations to required checks in .asf.yaml
* Fix path quoting in demo cluster creation script
