hook-scripts: Move smb hooks to right place.
Moved the hook-scripts to dirs corresponding to event. Also, edited S30samba-set.sh to with changes in other two hook scripts to bring uniformity.

+#TODO: All gluster and samba paths are assumed for fedora like systems.
+#Some efforts are required to make it work on other distros.
+
+#The preferred way of creating a smb share of a gluster volume has changed.
+#The old method was to create a fuse mount of the volume and share the mount
+#point through samba.
+#
+#New method eliminates the requirement of fuse mount and changes in fstab.
+#glusterfs_vfs plugin for samba makes call to libgfapi to access the volume.
+#
+#This hook script automagically creates shares for volume on every volume start
+#event by adding the entries in smb.conf file and sending SIGHUP to samba.
+#
+#In smb.conf:
+#glusterfs vfs plugin has to be specified as required vfs object.
+#Path value is relative to the root of gluster volume;"/" signifies complete
+#volume.
