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.

Before a7a3658 the rbdmap script was logging bogus messages and not working
on systemd platforms because the unit file was not defining the RBDMAPFILE
environment variable.
This workunit asserts that the bug has been fixed.
