[FEATURE]: Add external reference type for support policy/lifecycle metadata

[ppkarwasz]

Describe the feature

While the work on CLE is progressing it would be useful to add an externalReference type to hold a link to a CLE, OpenEOX or other kind of document that describes the versioning/support policy of the project.

Possible solutions

Naming is certainly the most difficult problem, but the new type might be called support-lifecycle or simply lifecycle.

Currently there is no machine-readable format to describe EOS/EOL data, but the link could point to a human-readable page.

FYI: the topic is currently in stage "proposal". A working implementation/spec via pull-request would set it to "prototyp".
When you are happy with your prototype, you can request to have it moved to "draft" - at this stage the community is asked to vote/comment the feature/implementation - and after 4 weeks the votes are counted and future steps might happen.

Sure, I'll send a PR by the end of the week. Can you assign me to the issue, so I don't forget?
