Subject: [PATCH] MDEV-32611: Test suite is missing dump option
 delete-master-logs.

Extending the rpl_mysqldump_slave.test to incorporate the
delete-master-logs option, and this options is alias of
get binlogs: show master status -> flush logs -> purge binary logs to <new_binlog>
sequence and this test is derived using the same pattern.
also we measure the pre and post log state
on the master following the mysqldump process. Introducing
assertions to validate the correct state.
