[FSunstone] multiple issues with image pool view

[dann1]

Description
Given the following image list

root@ubuntu2204-kvm-qcow2-6-8-zm1vb-0:~# oneimage list
  ID USER     GROUP    NAME                                                                                                                  DATASTORE     SIZE TYPE PER STAT RVMS
   7 oneadmin oneadmin Windows 11                                                                                                            default        20G OS    No used    2
   3 oneadmin oneadmin Ttylinux - KVM                                                                                                        default       200M OS    No rdy     0
   0 oneadmin oneadmin alpine                                                                                                                default       256M OS    No rdy     0

FireEdge displays it like this

The problems are

• none of the images are persistent

root@ubuntu2204-kvm-qcow2-6-8-zm1vb-0:~# oneimage show 0 | grep PERSISTENT
PERSISTENT     : No
root@ubuntu2204-kvm-qcow2-6-8-zm1vb-0:~# oneimage show 3 | grep PERSISTENT
PERSISTENT     : No
root@ubuntu2204-kvm-qcow2-6-8-zm1vb-0:~# oneimage show 7 | grep PERSISTENT
PERSISTENT     : No

• the running VMs icon is displaying something/something like the 2/2 Windows image, when it should really be just an integer, ex. 2
• Also maybe the image type (file for this images) could be displayed differently.
  • As it stands right now is displaying the type based on DISK_TYPES=%w{FILE CD_ROM BLOCK RBD}.
  • Instead it will probably be more informative to use IMAGE_TYPES=%w{OS CDROM DATABLOCK KERNEL RAMDISK CONTEXT BACKUP}
  • The problem is that there are FILE type images for FILE datastores, like the KERNEL and RAMDISK images. Having an icon mapping based on those will (most likely) result in a clearer example of what the image type actually is. The difference between FILE and RBD only matters to the hypervisor.

To Reproduce
View Image section under Storage section

Expected behavior

• Persistency displayed based on image persistence
• Running VMs should be just an integer
• The image type icon displayed could be improved to avoid confusion

Progress Status

• Code committed
• Testing - QA
• Documentation (Release notes - resolved issues, compatibility, known issues)
