APPLY IN THE TABLE NAMES

MySQL-5.7.2 introduced 6 replication P_S tables namely

(1) replication_connection_configuration Table
(2) replication_connection_status Table
(3) replication_execute_configuration Table
(4) replication_execute_status Table
(5) replication_execute_status_by_coordinator Table
(6) replication_execute_status_by_worker Table

In this patch we replace all usage of the word
"execute" by "apply" in tables (3) to (6).

So the table names become:

(3) replication_applier_configuration Table
(4) replication_applier_status Table
(5) replication_applier_status_by_coordinator Table
(6) replication_applier_status_by_worker Table

- Made changes in test and result files accordingly
