Add the notrim option to the rbd map command to avoid
discarding allocated blocks from a fully provisioned image,
and add the description of notrim option to manpage.
When enabled, user programs such as mkfs.xfs will receive -EOPNOTSUPP
if it sends a discard request for an image with this option.

Reuse rbd map -o infrastructure to expose rbd unmap options in
a similar fashion. Currently it's just one bool option, but we may
need more in the future.

Currently, we have a bench-write for in rbd tool, but we don't have
a simple bench for read.
This patch add a new subcommand of bench, with an option of --io-type.
Then we can do a simple bench for write or read.

rbd bench-write is going to be deprecated. This patch
makes it invisible in help message and manpage. But it
is still working.

Add a subcommand, rbd snap limit set <image> --limit <integer>, to
limit the number of snapshots that may be made of a given image.
To clear, use rbd snap limit clear <image>. Add an omap
key, 'snap_limit' to the RBD header for implementation. Add object
classes to set and query the limit. Older OSDs will ignore the limit.

The rbd cli will warn about the deprecation when attempting to create
image format 1 images. librbd will log an error message when opening

Object size can be specified when creating an image with the --order option,
as a number of bits in the size.
This patch is adding new option --object-size. This new option will specify
object size directly for example --object-size 2M.
It would be easier to use. --order is still present for backwards compatibility.
For simplicity, we are rounding up the object size to the nearest power of 2.
