I tried to create a subfolder of Archive, and it inherits the Archive  
quota's and partition's. And if I move that folder underneath INBOX,  
it takes the quota root and partition of INBOX. So this mechanism  
seems to work in Cyrus-Imapd 2.4.17.

I only need to set the partition and quota for Archive folder on each user.

An ipurge for archive (or an annotation as cyr_expire) is what I would  
like. I'm sorry of this lack.
