The following operations may fail right after a block device
is attached:
* retrieving the disk number (can return -1)
* opening the disk
* setting the disk online or writable
For this reason, we'll need to add some retries. For convenience,
we're moving the existing retry logic to a separate decorator.

Instead of trying to use the first partiton which may be reserved
by Windows, we'll fetch the first non-empty drive letter from
the disk that we've just mounted.
While at it, we're ensuring that the drive letter is actually a
letter and not a null character, which the Powershell command
returns in case of empty drive letters.

Its easy to "overload" a directory object with large number of omap entries by
doing the following (one shot or over and over again):
- touch dir/file{0..11000} ; create 11000 files (> mds_bal_split_size)
- mkdir dir/.snap/snap_a
- rm -f dir/file{0..11000}
End result - the directory object would have 11000 omap entries since the MDS
does not fragment directory snapshots. If the number of such entries exceed
`osd_deep_scrub_large_omap_object_key_threshold` (default: 200000), a cluster
health warning is generated:
Large Omap objects found in pool...
CDir::should_merge() does not take into account COW'd inodes and the frags
get merged.

As noted in commit 89177d6598 ("qa: switch to https protocol for
repos' server"), git.ceph.com mirror doesn't make git:// available
anymore. However, run_xfstests-obsolete.sh has "obsolete" in its
name for a reason -- due to an ancient execution environment, git://
is the only viable option:
$ git clone https://git.ceph.com/xfstests-dev.git
Cloning into 'xfstests-dev'...
error: gnutls_handshake() failed: A TLS fatal alert has been received. while accessing https://git.ceph.com/xfstests-dev.git/info/refs
fatal: HTTP request failed
Ditch git.ceph.com mirror for now.
