test/pybind/rbd: fix read offset in write zeroes tests
Random data is written and write zeroes is invoked on 0~256, but the
read is done on 256~256. This means that if write zeroes malfunctions
the test wouldn't catch it (especially in the thick provision case).

librbd: fix a deadlock on image_lock caused by Mirror::image_disable()
With Mirror::image_disable() taking image_lock for write and calling
list_children() under it, the following deadlock is possible:
1. Mirror::image_disable() takes image_lock for write and calls
list_children()
2. AbstractWriteLog::periodic_stats() timer fires (it runs every
5 seconds) and ImageCacheState::write_image_cache_state() is called
under a global timer_lock
3. ImageCacheState::write_image_cache_state() successfully takes
owner_lock and blocks attempting to take image_lock for read because
it's already held for write by Mirror::image_disable()
4. list_children() blocks inside of a call to ImageState::close() on
a descendant image
5. The descendant image close can't proceed because TokenBucketThrottle
requires a global timer_lock to complete QosImageDispatch shutdown
6. safe_timer thread which is holding timer_lock can't proceed because
ImageCacheState::write_image_cache_state() is effectively blocked on
the descendant image close through Mirror::image_disable()
Until commit 281a64acf920 ("librbd: remove snapshot mirror image-meta
when disabling"), Mirror::image_disable() was taking image_lock only for
read meaning that this deadlock wasn't possible. The only other change
that commit 281a64acf920 made to the code block protected by image_lock
was using child_mirror_image_internal for cls_client::mirror_image_get()
call on descendant images instead of mirror_image_internal to preserve
the value of mirror_image_internal for later. Both are local variables
that have nothing to do with image_lock, so I'm going back and making
Mirror::image_disable() take image_lock only for read again.

The documentation on dynamic resharding is updated to include a) a
description of reducing the number of shards, b) related configuration

rgw: add radosgw-admin sub-command to set-min-shards for a bucket
There is now a mechansim to set the minimum number of shards when a
bucket is created, and dynamic resharding adheres to that
setting. This adds the ability to modify that minimum shard count that
exists within the bucket layout of the bucket instance
object. Example:

rgw: allow per-bucket minimum number of shards
Dynamic resharding can now reduce the number of shards. The code
currently has a hard-coded value of 11 as the minimum number of shards
dynamic resharding can reshard to. There may be cases where the user
wants to set an alternate minimum, such as when they have a sense of
how many objects the bucket will eventually hold.
This PR builds off of https://github.com/ceph/ceph/pull/61269 .
That PR allows the user to specify an initial number of shards during
bucket creation. This PR then takes that number to be the minimum and
saves it in the layout field of the bucket instance object
(RGWBucketInfo).
When dynamic resharding is triggered, it will use that stored value as
a minimum number of shards for resharing.

msg: add alternate statuses for ms_dispatch2 handling
Many dispatchers return false to allow other dispatchers also common messages
like MOSDMap or MFSMap. They implicitly depend on some dispatcher which is
always at the "tail" of the dispatcher queue to return "true" indicating the
msg was processed to avoid messages like:
but this cannot always happen when some libraries like the RadosClient used standalone.
So, add a variant for encapsulating other indications for how the message was
processed by dispatch2. For example, a message may be "acknowledged" but
explicitly allow other dispatchers to try processing the message.
Note: we're using a variant to avoid updating all of the ms_dispatch code to
use the sentinel classes.
