CP-5818: Productise removal of lvm2-lvcreate-inactive-flag.patch

Snapshot and leaf coalesce operations use journaling files with
additional info like parent UUID in the name of the file. Since the
resultant file name is too long for LVM, the file was created in an
inactive mode. This patch changes the logic to create a journal file
with a shorter name and writes additional informaton into the file.
Inactive flag for lvcreate is no longer required.

This changeset includes the fix made for ticket [CA-117034].

VDI has driver name set to nbd in case VM migration failed. While
unpause tapdisk, it was always using mirror driver name. In a snapshot
failure scenario, the fix will pass None as driver name to unpause
tapdisk.

CA-121481: Ensure root disk is not blacklisted if booting from SAN

By default, every device is blacklisted, unless explicitly managed
by the Storage Manager.
When the root disk is managed by multipath, this happens at boot
time and the initrd must be able to add the device to multipath.
This patch ensures that, if the root disk is multipathed, it is
never blacklisted.

This patch can only guarantee that multipath is not broken for
the root disk but it is not responsible for making it multipathed
in the first place.

To make it working at installation time, dracut or mkinitrd should
call it explicitly.

CA-121481: No need to use the daemon

The script does not need the daemon to get the needed info.
This script is executed both as a standard boot script and
during the installation ensure the root disk is whitelisted.
In the latter case the daemon is not supposed to be running
but the root disk can be managed by the device mapper.

CA-121481: /dev/root does not exist at installation time

sm-multipath was meant to start at run time only.
We use this function to fix boot from SAN at installation time, too.
We cannot rely on /dev/root so we borrowed some utility functions
from dracut with a slight modification

CA-115035: mpath-boot and multipathed host other-config keys missing

Before upgrading to the new kernel, the output of
multipath -k"show maps"
and
echo "show maps" |multipathd -k
were different.

Now they are the same but previous code in mpathcount.py was
relying exclusively on the wrong output in the previous version.

Now it is fixed in both cases
