Retry remote state download while bootstrap #15950

Description

When a remote state enabled cluster manager node boots-up, it tries to download the remote state. But if there some issue while downloading like file not present then the download fails with an exception. The OpenSearch process stays active but unresponsive. This PR addresses this by:

  • Adding retries to the download to mitigate the issue where the node is trying to download a stale cluster state
  • If the retries fail, bail out by throwing an Error so that process exists and a new process is spawned.
