Healthcheck was incorrectly excluding non-local cell tablets. This fix ensures that healthcheck will connect to and monitor all tablets in cells_to_watch. However, only tablets that are MASTER/local cell/same cell alias will be stored in the list of healthy tablets.
Fixes #6846

Testing:

  • added unit tests
  • manually tested with local multi-cell cluster
