When a primiry image is being deleted, the mirrored image might
temporary be reported in error state, before deletion is propagated.

- log to stderr;
- log status if a `wait_for` function failed;
- don't needlessly sleep in `wait_for` functions after the last
unsuccessful iteration;
- make `wait_for_pool_images` work for image removal case;
- fix `wait_for_pool_images` reset timeout (last_count set).

Snapshot rename operations utilize the (cluster) unique snapshot
sequence to prevent attempts at replays. When mirroring to a
different cluster, these sequences will not align.

If an image is being bootstrapped, it implies that the rbd-mirror
daemon currently has the image open. The removal API will prevent the
removal of any image that is opened by another client.

This will help to test edge cases where the remote image does
or does not own the exclusive lock when the sync starts.

With the changes to ensure that the commit position of a new
client is initialized to the minimum position of other clients,
the 'journal inspect/export' commands return zero records because
the master client has committed all of its entries.
Workaround this by restoring the initial commit position after
writing to the image.

The debug messages from 'rbd bench-write' and 'rbd snap create',
in addition to the existing debug messages from rbd-mirror, make
it possible to determine the source of any image inconsistency.

This test repeatedly runs rbd bench-write, kills the process
randomly to create an unclean journal shutdown, and verifies
that the image content replicates correctly.

rbd_map_image() echoes the id of the image and is used in command
substitution:
id=$(rbd_map_image "${image}")
Output from rbd map isn't consumed and clobbers the return.

This is a followup to 38a572011d ("qa: rbd/map-snapshot-io.sh: don't
chown sysfs files") for the rest of the workunits:
- /sys/bus/rbd/add_single_major is used if present, so chown'ing
/sys/bus/rbd/add doesn't help. Use sudo on rbd map instead.
- Don't modprobe or udevadm settle - rbd CLI tool takes care of that.

Initially the asok commands were registered only after the image
replayer start (and unregistered on stop) because their names were
built using remote pool and image names, which became known only after
start.
Now, the asok commands are registered on the image replayer construction
using the temporary name "remote_pool_name/global_image_id". They are
re-registered using "remote_pool_name/remote_image_name" when the
image replayer is started. Also the commands are not unregistered on
the image replayer stop.

With these set, this script can work in teuthology, where we want to
control the how daemons run and their log locations, valgrind
settings, etc. The workunit task always sets CEPH_ID, and allows
other env vars to be configured optionally.
The RBD_MIRROR_USE_EXISTING_CLUSTER option can also speed up local testing.

Daemon name is only useful to differentiate asok and pid filenames, so
just inline its use there. Everywhere else replace the 'daemon'
parameter with cluster or local_cluster as appropriate.
Remove the CLUSTER{1,2}_DAEMON vars as well, since they are no longer
used.
