Update rbd-openstack.rst
In the original file, the increasing and decreaing of the size of the rbd block shares the same option:
"rbd resize --size 2048 foo".
However, it is not proper, as the "--allow-shrink" needs to be added while decreasing the size of the rbd block.
As a result, it is necessary to make a distinguish between these two options as follows:
"rbd resize --size 2048 foo (to increase)"
"rbd resize --size 2048 foo --allow-shrink (to decrease)"

To actually get the benefit of writeback caching, qemu must be
aware of it so it pases flushes to rbd. Since hammer rbd caching
is enabled by default, so add the nova option to make qemu aware
of it.
