Doc Text librbd SSD-based persistent write-back cache to reduce latency

With this release, the pwl_cache librbd plugin provides a log-structured write-back cache targeted at SSD devices. Just as with the already provided log-structured write-back cache targeted at PMEM devices, the updates to the image are batched and flushed in-order, retaining the actual image in a crash-consistent state. The benefits and use cases remain the same, but users no longer need to procure more expensive PMEM devices to take advantage of them.
