Prometheus exporter

[harmjanblok]

Describe the solution you'd like
A prometheus exporter which exports the EoL dates for one or more products as prometheus metrics.

Various exporters already provide metrics with the version an application is using, for example the node_exporter provides a node_os_version:

node_os_version{container="kube-rbac-proxy", endpoint="https", id="centos", id_like="rhel fedora", job="node-exporter", name="CentOS Linux", namespace="monitoring-system", pod="node-exporter-928p9", service="node-exporter"} 7

With a prometheus exporter for EoL dates both metrics could be used to display or alert if a current used version is EoL (or EoL soon).

Thanks for opening your first issue here! Be sure to follow the issue template!

This is an interesting idea!

I'm considering using node_supported_versions etc as the key to list down supported versions. That would be helpful in writing rules (you only need to match what's running).

Does that sound reasonable?

Could you provide sample metrics for how this might look, and how the corresponding alert rules would look?

@reimlima just developed one : https://github.com/reimlima/endoflife_exporter.

See #6900.
