Adds documentation how to change default rbd object size. With the
previous option `--order` it was easy to guess the config name for the
default value, with the current option name `--object-size` thats hard
to guess.
Also extends the documentation for rbd_default_order to include
* how object-size is derived from the configured value
* allowed range of the value
In the first version of this commit I also added min and max for this
parameter (12/25, matching the object size range in `man 8
rbd`/Striping/object-size), but this made some tests fail, since some
seem to set values outside this range (and probably are fine since
included for some time already). To have this a doc-change only, I
removed the range.

now that 067681b701
has been merged upstream, and our src/seastar submodule includes
this commit. there is no need to worry that the seastar's lockless
allocator does not work with seastar::alien anymore.

Add Release Notes and remove any `profile`
related stuff in the autoscaler documentation
and replace it with `bulk` flag.

Creating the pool with `--bulk` will allow
the pg_autoscaler to use the `scale-down`
mode on.
Creating pool:
`ceph osd pool create <pool-name> --bulk`
Get var:
`ceph osd pool get <pool-name> bulk`
Set var:
`ceph osd pool set <pool-name> bulk=true/false/1/0`
Removed `autoscale_profile` and incorporate bulk flag
into calculating `final_pg_target` for each pool.
bin/ceph osd pool autoscale-status no longer has
`PROFILE` column but has `BULK` instead.

This PR removes mentions of journaling from the hardware
recommendations.
Journaling was a FileStore-related practice. BlueStore is
the default backend for Ceph OSDs and has been since
Luminous. The documentation should reflect that.

Problem:
The MDS only stores the symlink inode's backtrace
information in the data pool. During disaster
recovery of the metadata pool by scanning data
pool, the symlinks are recreated as regular files.
Solution:
This patch stores the symlink target on the first
data object as an xattr for recovery.
MDS option:
The mds option 'mds_symlink_recovery' is introduced
which is enabled by default. Enabling the option
stores the symlink target.

Up until this point, we included aggregated and separated data for
testing purposes. Now that we've done our testing, the aggregated
metrics are no longer relevant.
Aggregated metrics can still be achieved on the server side by
summing separated metrics.
