List running applications on running servers using wsadmin scripting

Use wsadmin.sh and scripting to list all the running applications on all the running servers.

Use the following example to list all the running applications on all the running servers on each node of each cell.

### Jacl

#----------------------------------------------------------------
# Find all the cell and process them one at a time
#----------------------------------------------------------------
set cells [$AdminConfig list Cell]
foreach cell $cells {
   #-----------------------------------------------------------------------
   # find all the nodes belonging to the cell and
   # process them at a time
   #-----------------------------------------------------------------------
   set nodes [$AdminConfig list Node $cell]
   foreach node $nodes {
      #--------------------------------------------------------------
      # find all the running servers belonging to the cell
      # and node, and process them one at a time
      #--------------------------------------------------------------
      set cname [$AdminConfig showAttribute $cell name]
      set nname [$AdminConfig showAttribute $node name]
      set servs [$AdminControl queryNames type=Server,cell=$cname,node=$nname,*]
      puts "Number of running servers on node $nname: [llength $servs]"
      foreach server $servs {
          #---------------------------------------------------------
          # Get some attributes from the server to display;
          # invoke an operation on the server JVM to display a property.
