mgr/devicehealth: skip null pages when extracting wear level
Some devices have null pages in their ata_device_statistics struct; skip
those pages in order to avoid an AttributeError when extracting device's
wear level.
osd: Write non-zero data as part of osd benchmark test.
An optimization (see PR: https://github.com/ceph/ceph/pull/43337) was made
in BlueStore to avoid writing bufferlists made up of zeros. The osd
benchmark used zero filled bufferlists and this resulted in inflated osd
benchmark results.
This issue is fixed by using bufferlists filled with non-zero values.

rbd-mirror: synchronize with in-flight stop in ImageReplayer::stop()
Complete on_finish right away only if the replayer is stopped (meaning
that it is legible to be restarted immediately, possibly from on_finish
itself). This is the behaviour pretty much anyone would assume and
also what ImageReplayer::restart() relies on.

rbd-mirror: straighten ImageReplayer::stop() a bit
- don't default on_finish parameter
- m_restart_requested is set in ImageReplayer::restart() which is the
only restart=true call site, so setting m_restart_requested here is
redundant
- is_stopped_() can't be true in is_running_() branch
- on_finish->complete(0) in the end is unreachable

seastore: seperate Journal interface from SegmentedJournal implementation
A subsequent PR will introduce a CircularBoundedJournal implementation
for fast nvme devices.
SegmentCleaner no longer needs a reference to Journal, so dispense with
the set_segment_provider machinery and simply pass it in the
constructor.
Move responsibility for finding the journal segments into the journal
itself. This does mean that we check the segment headers on the journal
device twice, but that should be a neglible amount of overhead on mount.
SegmentCleaner::init_segments no longer needs to return Journal
segments, so merge with mount().

rbd-mirror: make mirror properly detect pool replayer needs restart
When a PoolReplayer detects remote pool metadata change it
sets "stopping" flag expecting the Mirror will restart it.
Although setting "stopping" flag makes the PoolReplayer::run
thread to terminate, the thread's is_started function will still
return true until join is called (and reset the thread id).
This made impossible for the Mirror to detect (by calling
PoolReplayer::is_running) that the PoolReplayer needed restart.

rbd: avoid get_callback_adapter() for tcp_stream::async_connect()
works around a compilation failure in c++20 (with gcc 11.2 and boost
1.76) when choosing between two overloads of
`boost::beast::tcp_stream::async_connect()`
`get_callback_adapter()` returns a variadic lambda that matches the
concept for both overloads (`completion_token_for<ConnectHandler>`
and `completion_token_for<RangeConnectHandler>`), but compilation of
the wrapped lambda fails for the `ConnectHandler` overload because it
expects two arguments instead of one
instead of using `get_callback_adapter()` to convert the first argument
from `boost::system::error_code` to `int` for the wrapped lambda, do
this in the lambda itself

mgr/telemetry: handle empty device report when "send" is triggered
On certain environments, such as the "ceph-dev-docker" environment
(https://github.com/ricardoasmarques/ceph-dev-docker), the mgr
module is unable to fetch device metrics. As a result, the device
report generated by "gather_device_report()" returns an empty dict.
This causes an AssertionError when the "send" function is triggered
(i.e. by running `ceph telemetry status` or `ceph telemetry send`),
and the module crashes.
The fix in this commit checks that the generated device report
contains metrics before trying to send it. If the device report
does not contain metrics (it returns an empty dict), the module
will log an appropriate message in the mgr log and not send the
device report.
If this scenario happens when running the `ceph telemetry send` command,
the user will additionally see this message:
```
Ceph report sent to https://telemetry.ceph.com/report
Unable to send device report: channel is on, but generated report was empty.
```
I also added a few more debug messages in gather_device_report() to make
future debugging easier.

common: replace BitVector::NoInitAllocator with wrapper struct

preventing the no-init optimization from taking effect
instead of messing with the allocator to avoid zero-initialization, wrap
each __u32 in a struct whose constructor does not initialize the value
