Whenever a dev node that is not in use is opened with open(O_RDWR)
udev triggers a flush in devtmpfs that briefly remove & recreate all
the nodes for partitions on that device. This leads to commands
accessing dev nodes during the flush to fail. In our case blkid and
lsblk failed.
These failures are hard to reproduce, have devastating effect on
the partitioning operations and are not solved by using 'udevadm settle'
as some of the kernel events are asynchronous.
So, mainly, this commit stops udev from messing up with /dev nodes by
initializing file descriptors for all storage devices then opening
locks on them with flock. Setting locks stops udev triggering kernel
partition rescan.
Locks are set at the start of the partitioning operation and
released at the end.

This commit:
o stops udev messing up with /dev nodes;
o aborts install on critical failures;
o adds retry for critical operations such as LVM cleanup or
partition removal and creation.
