doc: highlight that "raw" is the only useful RBD format for QEMU
...
Explain why people should be using the "raw" image format for RBD
volumes created for use by QEMU: using any other format adds only
overhead, but no extra value (since RBDs are also CoW and
thin-provisioned), plus the Qcow2 storage driver is not migration safe
when caching is enabled, whereas the RBD driver is.
Also, fix a minor glitch in the example qemu-img commands ("-f rbd"
and "-O rbd" should really be "-f raw" and "-O raw").
Finally, drop the "-f" option altogether on qemu-img commands where it
makes no sense (info and resize).

librbd: optionally wait for a flush before enabling writeback
...
Older guests may not send flushes properly (i.e. never), so if this is
enabled, rbd_cache=true is safe for them transparently.
Disable by default, since it will unnecessarily slow down newer guest
boot, and prevent writeback caching for things that don't need to send
flushes, like the command line tool.
