MDEV-9544 FLUSH [RELAY] LOGS does not rotate logs for a named slave9544

Problem:- In the case of multisource replication/named slave
when we run "FLUSH LOGS" , it does not flush logs.

Solution:- A new function Master_info_index->flush_all_relay_logs()
is created which will rotate relay logs for all named slave.
This will be called in reload_acl_and_cache function when
connection_name.length == 0
