Imap connection caching

Migrated from PHPCAS-121

Description

Implement some kind of connection caching for imap. It should be possible to cache the opened streams somehow. PHP5 should support this (like for DBs). I have to investigate this and implement a solution.

I know it's been 10 years, but if you tried something, had something in mind at some point (or even found a solution !), I'd like to hear it 😄 I'm facing the same issues and I'm trying to find the right way to fix this (and I'd love to contribute, of course).
