This code is processing event execution and does not have client
connection. Here, event execution will now execute a prepared
DROP EVENT statement, but thd->lex->sql_command is set to
SQLCOM_CREATE_PROCEDURE
DROP EVENT will be logged in binlog, and we have to
replicate it to make all nodes have consistent event definitions
Wsrep DDL replication is triggered inside Events::drop_event(),
and here we need to prepare the THD so that DDL replication is
possible, essentially it requires setting sql_command to
SQLCOMM_DROP_EVENT, we will switch sql_command for the duration
of DDL replication only.
