work_mem check for nagios client

[Michal Novotny]

Hello,

I've noticed there is no work_mem check
https://infrastructure.fedoraproject.org/cgit/ansible.git/tree/roles/nagios_...
that would test that working memory is inside allowed limits.

I've recently made the work_mem check but specific just to COPR:
https://clime.cz/0001-copr-fe-working-memory-monitoring.patch. It
raises a warning when working memory usage is higher than 80% and
criticial if it is higher than 90%.

Would it be worth to place this check alongside others in
https://infrastructure.fedoraproject.org/cgit/ansible.git/tree/roles/nagios_...
so that it can be used for any host?

Thank you
clime
