fix: upon DNS refresh() failure use previous values (#17561)

DNS refresh() in-case of MinIO can safely re-use
the previous values on bare-metal setups, since
bare-metal arrangements do not change DNS in any 
manner commonly.

This PR simplifies that, we only ever need DNS caching
on bare-metal setups.

- On containerized setups do not enable DNS
  caching at all, as it may have adverse effects on
  the overall effectiveness of k8s DNS systems.

  k8s DNS systems are dynamic and expect applications
  to avoid managing DNS caching themselves, instead
  provide a cleaner container native caching
  implementations that must be used.

- update IsDocker() detection, including podman runtime

- move to minio/dnscache fork for a simpler package
