Feature:
Improve protection against running OSD twice at the same time on one block device.
Reinforce advisory locking with O_EXCL open flag dedicated for block devices.
Reason:
We had protection against running BlueStore twice by using advisory locking.
This worked (and still works) very well on baremetal deployments.
However, when one uses containers it is possible to create unrelated inodes that target same block device "mknod b".
As a result, 2 containers can think they have exclusive access.
This almost always leads to severe errors.
Result:
It is no longer possible to open one BlueStore instance twice.
Some categories of weird overwrite and corruptions will now be gone.
