Return the latest known deprecations in the registry response of all versions for each package

[criamico]

Based on the deprecation lifecycle discussed in this RFC.

When a package becomes deprecated, it will still remain searchable to prevent a breaking change.

Return the latest known deprecations in the registry response of all versions for each package, if any. This would allow to see the warning even in cases where the package has been deprecated only for some kibana.version.

Example:

$ curl "https://epr.elastic.co/search?package=apache&all=true"
