描述

Jira Link: DB-1565 Reported by @hectorgcr.

Add new test to verify that a failure between call to RemoteBootstrapClient::Finish() and OpenTablet doesn't leave the tablet server in an invalid state. Ideally, since the tablet gets tombstoned, the tablet server should be remote bootstrapped again by the leader, and the tablet server should reject any requests to participate in raft consensus rounds.

研究方向
Look at existing remote bootstrap tests in the docdb directory, such as tablet server test.cc or similar. The test should simulate a crash or failure after RemoteBootstrapClient::Finish() and before OpenTablet, then check that the tablet server remains in a valid state and can be re bootstrapped. Investigate the RemoteBootstrapClient class and OpenTablet function to understand the failure point.
