xenadmin/XenModel/Actions/VMSS/LoadVmssAction.cs
Konstantina Chremmou 37e3810d73 Removed the background worker and added an async action to retrieve the local
server time (previously on the UI  thread) and also update the message list
for each snapshot schedule. Preserve column sorting and multiple selection
when the list is rebuilt. Do not enforce minimum size on the form since it
is not resizable.
