Subject: Move RBD Cache on clients from RAM to SSD.

Hello.
By now rbd_cache uses RAM, can we store cache on disk (SSD, SSD NVE)?
In this way I look some benefits:
* Don't waste a RAM for cache
* Can make a big cache on SSD: 2-8Gb per cache
* If you use Cache Tier - don't waste space on them
* No need addition Ceph servers - use Compute with SSD.
Yes it's for write-through and read-only cache strategies mostly.
Any ideas? My be I am blind and this idea totally stupid?
