Check allowed file storage paths during cluster-verify

Some paths, such as /bin or /usr/lib, should not be used for file

Update blockdev's "info" at instance rename

Currently, we set "info" metadata on block devices at device creation

If normal file storage was disabled but shared storage enabled,

Move a function from backend to ssconf

The “WriteSsconfFiles” function is used to write ssconf files. By moving
it we can avoid importing backend into bootstrap. The latter is imported
by CLI programs and backend doesn't have much to do with them.
