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.

also switch to that user's gid, unless --setgroup is also specified.

--object-extents is a bit confusing - extent is generally something of
a varying length and here the meaning is "diff whole objects". Rename
it to --whole-object (the name of diff_iterate() parameter).

Change du to take <image-spec> | <snap-spec> as an argument instead of
going through --image option. The new synopsis is
(du | disk-usage) [<image-spec> | <snap-spec>]
This is to make it look more like the rest of the commands: the only
other command that takes pool as an argument is ls and it can't really
serve as a prototype for du, because the latter has to work on images
and snapshots as well.
Examples:
# stats for pool rbd
$ rbd du
$ rbd -p rbd du
# stats for pool foo
$ rbd -p foo du
# stats for snapshot mysnap of image baz in pool rbd
$ rbd du baz@mysnap
# stats for image bar in pool foo
$ rbd du foo/bar

Mark those as such in help and clarify what image-spec defaults to.
Related, all command args in our man page are enclosed into brackets.
I suppose the reason is that they are optional in the sense that you
can have commands like
$ rbd clone --pool a --image b --snap -c --dest-pool d --dest e
with no args. Given that we are trying to push people towards
$ rbd clone a/b@c d/e
undo that so that real optional arguments can be marked optional.
While at it, add synopsis for each command and use backticks for
denoting commands more consistently.

This patch changes image-name instances to image-spec and snap-name
instances to snap-spec to try to clarify usage for some commands and
disambiguate the term {image,snap}-name, which has been used to denote
both simple names and compound names (specs).
<image-spec> is [<pool-name>]/<image-name>
<snap-spec> is [<pool-name>]/<image-name>@<snap-name>
This patch also removes duplicate checks for image-name and snap-name.

Wip writeback throttling for cache tiering
This patch is to do write back throttling for cache tiering, which is similar to what the Linux kernel does for page cache write back. A paramter 'cache_target_dirty_high_ratio' (default 0.6) is introduced as the high speed flushing threshold, while leave the 'cache_target_dirty_ratio' (default 0.4) to represent the low speed threshold. The flush speed is controlled by limiting the parallelism of flushing. The maximum parallelism under low speed is half of the parallelism under high speed. If there is at least one PG such that the dirty ratio beyond the high threshold, full speed mode is entered; If there is no PG such that dirty ratio beyond the low threshold, idle mode is entered; In other cases, slow speed mode is entered.
