Version:	8.0.12	OS:	Any
Assigned to:		CPU Architecture:	Any

Description:
On WL#11568: "Group Replication: option to shutdown server when dropping out of the group" we did introduce the option group_replication_exit_state_action, which when set to ABORT_SERVER, in the case of a Group Replication error the server would be aborted by calling abort().

WL#12003: "Component interface to deliver signals to the host application" introduced a service through which a plugin can instruct the server to shutdown instead of calling abort().

This bug will replace the abort by the new shutdown service call.

Also this bug will remove the lines:
 --source include/have_debug.inc
 --source include/not_valgrind.inc
that were added to several tests to avoid MTR consider this expected behaviour a unexpected server crash.
The bug assigned must find which tests need to be updated, one of them is gr_exit_state_action_on_applier_error.test

How to repeat:
Please see abort_plugin_process() on plugin/group_replication/src/plugin_utils.cc

Suggested fix:
I will upload a draft patch.

Thank you for your feedback, this has been fixed in upcoming versions and the following was added to the 8.0.14 / 8.0.14 changelog:
When group_replication_exit_state_action is set to ABORT_SERVER, the Group Replication plugin now uses the new component service added by WL#12003 to shutdown MySQL.
