We can get random messages to stderror from socket reconnects and such;
discard those if we are looking at stderr in the test.

If we add an item that already exists in particular position, we should
update instead of inserting it; the CrushWrapper methods are not

'ceph-conf ...' doesn't give you final/default values, only what is in the
conf file. Use -w output to test this instead.

The sysfs entries for snapshots went away a while ago, and this
script used them to verify sizes matched what was expected.
Instead, look at the mapped size of the snapshot in the places
that used to look for the image's snapshot sysfs files.
Also, switch over to using "udevadm settle" rather than a delay to
wait for udev to do its thing. Insert them at more appropriate
places--right after "rmd map" commands and before and after the
"rbd unmap" calls.
Stop doing the manual refresh calls as well. The osd will trigger
refreshes whenever the image size or shapshot context changes.
Finally, the cleanup routine is called initially, when there really
isn't expected to be anything to clean up. Change the rbd commands
to run there conditionally, only if the target of the command
already exists.

There's no guarantee the rbd module is loaded when this script is
run, so add a line that loads it if necessary.

An rbd clone image can be created with an object order that differs
from that of its parent. This patch adds testing for that in
qa/workunits/rbd/image_read.sh. By default, clone images will be
created with an object size twice as big as that of its parent.
For simplicity, when a clone's object order differs from its parent
the order will be either one more than or one less than that of its
parent image, meaning its object size is either double or half of
the size of objects used in the parent.

The function boolean_toggle() in qa/workunits/rbd/image_read.sh is
defined but never used. My intentions were good though. Fix it and
use it for argument parsing.
Change the minimum supported object order so it matches what the
command line interface enforces.
Assign the initial value of TEST_CLONES from the environment if it's
available.
Change defaults to use format 2 and test clones.
Output details about the parameters of the run even if not being
verbose.
Make the order of assignment of argument variables consistent.
And fix a typo unmap_image().

Since snapshots never change, it's safe to read from replicas for them.
A common use for this would be reading from a parent snapshot shared by
many clones.
Convert LibrbdWriteback and AioRead to use the ObjectOperation api
so we can set flags. Fortunately the external wrapper holds no data,
so its lifecycle doesn't need to be managed.
Include a simple workunit that sets the flags in various combinations
and looks for their presence in the logs from 'rbd export'.
