HBASE-29503: IntegrationTestBackupRestore is passing even if an exception occurs in the thread(s) it creates

[kgeisz]

https://issues.apache.org/jira/browse/HBASE-29503

This is a cherry-pick of PR #7203, which was merged into master as d80bbef.

Currently, IntegrationTestBackupRestore is creating a separate thread to run the full/incremental backup and restore processes. With this implementation, if an exception occurs in this thread, then an error will be logged but the integration test will still pass. I initially noticed this while working on HBASE-29411. I also observed this behavior when I did not have changes from PR #7151 in my branch.

This pull request turns the backup/restore thread into an actual class that implements Runnable. Within this class, there is an instance variable that starts as null and records any exceptions that occur. The main thread checks this instance variable when it joins the thread. If this instance variable is not null, then the recorded exception is thrown.
