hooks: add a script to stat the subdirs in add-brick

The subdirectories are expected to be present for a subdir
mount to be successful. If not, the client_handshake()
itself fails to succeed. When a volume is about to get
mounted first time, this is easier to handle, as if the
directory is not present in one brick, then its mostly
not present in any other brick. In case of add-brick,
the directory is not present in new brick, and there is
no chance of healing it from the subdirectory mount, as
in those clients, the subdir itself will be 'root' ('/')
of the filesystem. Hence we need a volume mount to heal
the directory before connections can succeed.

This patch does take care of that by healing the directories
which are expected to be mounted as subdirectories from the
volume level mount point.
