Review 1/1/26 - Plan, Test, Deploy CAPI V3 version of Prometheus

[ChrisMcGowan]

In order to handle the CAPI V2 deprecation, Prometheus needs to be updated (mainly around the exporters that scrape data from CF) so we continue to have monitoring.

The release is maintained here: https://github.com/cloudfoundry/prometheus-boshrelease

CF Exporter has an issue on trying to do V3 only here: cloudfoundry/cf_exporter#142

Prometheus want to have a new version called V3 (assuming using latest calls/architecture) and is tracking it here: cloudfoundry/prometheus-boshrelease#504

[ChrisMcGowan]

Left a comment on the main thread for Prometheus3 looking for any updates. So far no new releases at all for Prometheus nor CF exporter.

Moving this ticket to BLOCKED status with a date of May 5th to review to see if upstream as cut new releases

[ChrisMcGowan]

So Prometheus3 is due out soon but cf-exporter which makes the CAPI calls, might not be fully updated with that release to be 100% V3 calls. See: cloudfoundry/prometheus-boshrelease#504 (comment)

[ChrisMcGowan]

Getting closer:
[v30.9.0](https://github.com/cloudfoundry/prometheus-boshrelease/releases/tag/v30.9.0) is the last with cf-exporter using CAPI v2
