Jira (PUP-8088) add mechanism for cache eviction callback / finalizers

[Henrik Lindberg (JIRA)]

Title: Message Title

Henrik Lindberg commented on PUP-8088   Re: add mechanism for cache eviction callback / finalizers Yes, still relevant, and I have an implementation. The use case is primarily to allow functions to hold a connection open and to close it gracefully. This is often a need in hiera backend functions. Without this they either have to open/close around every invocation (very expensive) or just leave connections open and let them time out (may run out of handles if timeout is long). I just pushed up the work - W.I.P, and I honestly don't remember how far I got, but there are tests etc. There is a draft PR here: https://github.com/puppetlabs/puppet/pull/7846 - question is if this is a good idea or not, something is most definitely needed.
