Glance has not completely moved to 'store' yet so we need to configure
the store in the DEFAULT section as well.

Enabling the RBD cache improves sequential IOs and the socket helps a
lot while troubleshooting. These 2 items are considered as best
practice for OpenStack deployments with Ceph.

rbd binary will load rbd.ko itself, with appropriate options. Loading
it by hand with default options is undesirable.

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).

- RBD Documentation, --image-format wrongly specified as --format in examples
- RBD Documentation, better describe image format, to differentiate from --format
