See issue #33128

We can't rely on the device name provided by Cinder, and thus must perform
detection based on the drive serial number (aka It's cinder ID) on the
kubelet itself.

This patch re-works the cinder volume attacher to ignore the supplied
deviceName, and instead defer to the pre-existing GetDevicePath method to
discover the device path based on it's serial number and /dev/disk/by-id
mapping.

This new behavior is controller by a config option, as falling back
to the cinder value when we can't discover a device would risk devices
not showing up, falling back to cinder's guess, and detecting the wrong
disk as attached.
