CSM Improve DS8000 Paths Interface

I would like to propose several enhancements to how the CSM DS8000 Paths screen is displayed and managed.

1) The DS8000 Paths screen has a lot of unused space when drilled down into a storage device list of paths, on my monitors at least half of the window is just empty space, and you must scroll down quite a lot to go through the list. It would be good if it could fill up most of the available window space, as the Sessions list does.

2) Unlike many other screens, eg Topology, Copy Sets, Sessions, &c, the Paths list does not have any row markers to keep the eye on the correct line in systems where there are many PPRC paths to manage.

3) As with above, eg in Sessions list or Copy Sets list within a session, if you hover over a line, it will highlight it in one color and if you select the line it will highlight it in a darker color. This would also help quite a lot to keep the user straight on which Paths are selected when one is doing bulk operations, eg removing a couple dozen unused Paths.

4) Under Manage Paths view, when one is choosing Ports, they are not in any order. When there are a number of ports to choose from, it would definitely help to have the Ports be sorted in order.

(Adding in additional improvements recommended by Guest back in March since I very much agree on all counts.)

5) The path panels should get a filter field like other panels have to quickly filter certain FCP ports or LSSes

6) The path tables should get a colum to indicate whether the path has CG mode enabled

7) The path panels currently do not show all failed path from the storage system (e.g. if target ports/system are unknown, or if paths have been frozen and are in a System reserved Failed state, they do not show up in CSM). So CSM path panel does not reflect the complete path picture as reported by DSCLI
