Sorting of items in panels is not done correctly when there is huge list

[Majety Sri Ashika Meher]

When trying to sort Flavors (e.g. per number of "VCPUs"), or Instances (e.g. per "Time since created"), in case of huge list spreading over two(2) or more sheets (pages), sorting mechanism sorts only list of Flavors or Instances on dedicated page. Further pages (e.g. 2nd) is not affected by sorting mechanism. But the sorting mechanism in Images panel sorts the entire list. This is because of difference in table implementations for panels in python and angular. So, all panels should be implemented in angular for proper sorting.
