Add bcache-export-cached helper to export CACHED_UUID and CACHED_LABEL always
Linux kernel bcache driver does not always emit a uevent[1] for when
a backing device is bound to a bcacheN device. When this happens, the udev
rule for creating /dev/bcache/by-uuid or /dev/bcache/by-label symlinks does
not fire and removes any persistent symlink to a specific backing device
since the bcache minor numbers (bcache0, 1, 2) are not guaranteed across reboots.
This script reads the superblock of the bcache device slaves,ensuring the slave
is a backing device via sb.version check, extracts the dev.uuid and
dev.label values and exports them to udev for triggering the symlink rules in
the existing rules file.

(cherry picked from commit 84558fec5f0e4ae5f38ac34dde1775d4eeb766e2)
bcache is a Linux kernel block layer cache. It allows
one or more fast disk drives such as flash-based solid
state drives(SSDs) to act as a cache for one or more
slower hard disk drives.
bcache-tools containes the userspace tools required for
bcache. Here we init bcache-tools package with v1.1 version.
