common-ha: add node create new node dirs in shared storage

When adding a node to the ganesha HA cluster, create the directory
tree in shared storage for the added node and create sets of symlinks
to match what is/was created for the other nodes.  I.e. in a four
node cluster the new node needs a set of links to the four existing
nodes:
 /run/gluster/shared/nfs-ganesha/$new/nfs/{ganesha,statd}/$e1 -> e1
 /run/gluster/shared/nfs-ganesha/$new/nfs/{ganesha,statd}/$e2 -> e2
 /run/gluster/shared/nfs-ganesha/$new/nfs/{ganesha,statd}/$e3 -> e3
 /run/gluster/shared/nfs-ganesha/$new/nfs/{ganesha,statd}/$e4 -> e4
and all the existing nodes need links added for the new node:
 /run/gluster/shared/nfs-ganesha/$e1/nfs/{ganesha,statd}/$new -> new
 /run/gluster/shared/nfs-ganesha/$e2/nfs/{ganesha,statd}/$new -> new
 /run/gluster/shared/nfs-ganesha/$e3/nfs/{ganesha,statd}/$new -> new
 /run/gluster/shared/nfs-ganesha/$e5/nfs/{ganesha,statd}/$new -> new

Likewise when deleting, remove the dir and symlinks.
