説明

Jira Link: DB-15477

Description

https://phorge.dev.yugabyte.com/diffusion/YBDB/browse/master/src/yb/tserver/remote_bootstrap_service.cc$394

  MonoTime now = MonoTime::Now();
  const string session_id = Substitute("$0-$1-$2", requestor_uuid, tablet_id, now.ToString());

allows for multiple RBS sessions for the same follower. This should be unnecessary and can lead to ooms if left uncontrolled.

We should only allow at most 1 pending RBS session for a follower, and end previous sessions when a new session is created.
