Amend the example output and drop the word "transient" -- currently it
is the exact opposite, as the status is updated only when the cache is
opened and closed.

Most of the Windows documentation is currently included in the
README.windows.rst file.
To make it more accessible, we're moving most of it to the
"doc/" folder, adding the following pages:
* Installing Ceph on Windows
* RBD on Windows
* Windows troubleshooting
We'll keep the build and manual install instructions in
README.windows.rst. Note that ceph-dokan already has a separate
doc page.

The initial implementation does not support backing files, compression,
snapshots, (deprecated) encryption, external data files, nor L2 subcluster
allocation. The former three features will be added in a future commit.

Ceph config option names may use spaces, underscores, or by one reference hyphens
as interstitial separators. Most usage within the doc tree uses underscores,
though example conf files and especially structured lists of options mostly
use spaces. Mostly. Underscores help differentiate the config names from
surrounding text, and moreover facilitate scripting, grep, awk, etc and match
their form in src/common/options.cc.
This PR conforms these occurrences of option names to use interstitial underscores instead of spaces.

The exclusive-lock could be transited transparently between clients
after finishing write operation. To disable "transparent" transition,
it needs to acquire the lock with RBD_LOCK_MODE_EXCLUSIVE.

so as to support continuous burst. The desired burst duration can be
controlled by rbd_qos_XYZ_burst_seconds.

RTD does not support installing system packages, the only ways to install
dependencies are setuptools and pip. while ditaa is a tool written in
Java. so we need to find a native python tool allowing us to render ditaa
images. plantweb is able to the web service for rendering the ditaa
diagram. so let's use it as a fallback if "ditaa" is not around.
also start a new line after the directive, otherwise planweb server will
return 500 at seeing the diagram.
