Review and update the use of flushing handlers.

[uk-bolly]

Summary of Request
Handlers are force flushed during the playbook, prior to reboot due to grub rebuild etc.

Review the logic regarding reboots and audit taking place to see if this is required
Is this purely for audit or reboot or just auditd?

It also runs twice.
Runs once in main.yml
then called by by main.yml in post.yml with the always tag.

Suggested Code
Look at only if not reboot?
and run_audit is checked?
