crimson/os/seastore: measure transactional efforts that are discarded or committed
The efforts of a transaction include the number and bytes of its read,
mutate, retire and fresh extents, and the bytes of delta generated.
This helps to understand the following aspects:
* The ratio of discarded efforts vs committed efforts;
* The average efforts of a transaction;
* The distribution of read/mutate/delta/retire/fresh efforts;
* The memory overhead and potential disk overhead of a transaction;
* How early a transaction invalidation happens;
* The average extent length;
It is possible to extend the effort metrics to be labeled by extent
types, in case we want to distinguish and profile the efforts at the
sub-component level.
crimson/os/seastore: assert the committing delta is not empty
It makes no sense to commit an empty delta. It is mostly an issue that
user forget to generate delta during mutation, or there are futile
copy-on-write operations.

mgr/cephadm: migrate all legacy nfs exports to new .nfs pool
Migrate all past NFS pools, whether they were created by mgr/nfs or by
the dashboard, to the new mgr/nfs .nfs pool.
Since this migrations relies on RADOS being available, we have to be a bit
careful here: we only attempt the migration from serve(), not during
module init.
After the exports are re-imported, we destroy existing ganesha daemons so
that new ones will get recreated. This ensures the (new) daemons have
cephx keys to access the new pool.
Note that no attempt is made to clean up the old NFS pools. This is out
of paranoia: if something goes wrong, the old NFS configuration data will
still be there.

This is a new pool that we can migrate all past NFS configuration to,

.-prefixed name).

Fetch the actually running selinux status.
The HostFacts should return the **actual** selinux mode in which the
kernel is running.
The actual mode can be different from the one in the configuration
if the server has not been rebooted or if the mode was changed
after boot using setenforce.
Instead of reading _selinux_path_list we should look at the output of
sestatus or getenforce.
The _selinux_path_list attribute is no longer needed.

librbd/cache/pwl/ssd: fix use-after-free on C_BlockIORequest
In setup_schedule_append() function, its first expression
will cause the req to be deleted, and subsequent use of
the variable req becomes an illegal operation. And due to
delete, rep->m_image_ctx will be empty, so it lead to
segfault in AbstractWriteLog::get_context().
So pass the `req` into `schedule_append()` function.

common/LogEntry: drop support of LogSummary v2 encoding scheme
LogSummary's v3 encoding scheme was introduced in 648aaf271cb02c647f046288656c11f15a7799b2, which was in turn included
by Ceph v13.1.0 and all newer releases. since LogSummary is persistented
by monitor, and it is trimmed regularly by monitor, there is no need
to read a LogSummary encoded by 2 releases older monitor.
in this change, the support of LogSummary v2 encoding scheme is dropped.
