ceph-disk: Adding retry loop in get_partition_dev()

There is very rare cases where get_partition_dev() is called before the actual partition is available in /sys/block/<device>.

It appear that waiting a very short is usually enough to get the partition beein populated.

Analysis:
update_partition() is supposed to be enough to avoid any racing between events sent by parted/sgdisk/partprobe and
the actual creation on the /sys/block/<device>/* entrypoint.
On our CI that race occurs pretty often but trying to reproduce it locally never been possible.

This patch is almost a workaround rather than a fix to the real problem.
It offer retrying after a very short to be make a chance the device to appear.
This approach have been succesful on the CI.

Note his patch is not changing the timing when the device is perfectly created on time and just differ by a 1/5th up to 2 seconds when the bug occurs.

A typical output from the build running on a CI with that code.
command_check_call: Running command: /usr/bin/udevadm settle --timeout=600
get_dm_uuid: get_dm_uuid /dev/sda uuid path is /sys/dev/block/8:0/dm/uuid
get_partition_dev: Try 1/10 : partition 2 for /dev/sda does not in /sys/block/sda

ceph-disk: Reporting /sys directory in get_partition_dev()

When get_partition_dev() fails, it reports the following message :
    ceph_disk.main.Error: Error: partition 2 for /dev/sdb does not appear to exist
The code search for a directory inside the /sys/block/get_dev_name(os.path.realpath(dev)).

The issue here is the error message doesn't report that path when failing while it might be involved in.

This patch is about reporting where the code was looking at when trying to estimate if the partition was available.

os/bluestore: fix OnodeSizeTracking testing

[  FAILED  ] 1 test, listed below:
[  FAILED  ] ObjectStore/StoreTest.OnodeSizeTracking/2, where GetParam() = "bluestore"

 1 FAILED TEST

The above test failure happens as the bluestore mount() process
will try to load all collections and put them into the coll_map,
which will be also tracked as mempool::bluestore_meta_other.
So total_bytes from mempool won't be equal to zero.

os/bluestore/BlueFS: fix flush_bdev placement

We need to flush any new writes on any fsync().  Notably, this includes
the rocksdb log. However, previously _fsync was only doing a bdev flush if
we also had a dirty bluefs journal and called into _sync_and_flush_journal.
If we didn't, we weren't doing a flush() at all, which could lead to
corrupted data.

Fix this by moving the first flush_bdev *out* of _sync_and_flush_log.  (The
second one is there to flush the bluefs journal; the first one was to
ensure prior writes are stable.)  Instead, flush prior writes in all of the
callers prior to calling _sync_and_flush_log.  This includes _fsync (and
fixes the bug by covering the non-journal-flush path) as well as several
other callers.

os/bluestore/KernelDevice: make flush() thread safe

flush() may be called from multiple racing threads (notably, rocksdb can call fsync via
bluefs at any time), and we need to make sure that if one thread sees the io_since_flush
command and does an actual flush, that other racing threads also wait until that flush is
complete.  This is accomplished with a simple mutex!

Also, set the flag on IO *completion*, since flush is only a promise about
completed IOs, not submitted IOs.

Document.
