 CLOUDSTACK-9718: Revamp the dropdown showing lists of hosts available for migration in a
Zone

    Reviewed-By: Rashmi Dixit

    Problem: All the hosts suitable for VM Migration are not shown in the UI. This could
    confuse the user as the target host might never be shown in the UI.

    Root Cause: The API (findHostsForMigration) always returned page 1 results which would
    be always <= default.page.size global parameter. Therefore, in case of large
    no. of hosts where the result can map to multiple pages, this issue would arise.

    Solution: 1. Replace drop-down with listView widget.
    2. Allow lazy-loading of records on listView's scroll.
    3. Show additional parameters (CPU/Memory used) to assist admin in decision making.
    4. Provide 'Search by host name' to limit the results.

Added change where if there are no hosts found, an empty row with message will
appear.

> There are a couple of issues:
> 1. When looking for the possible hosts for migration, not all are displayed.
> 2. If there is a large number of hosts, then the drop down showing is not easy to use.
> To fix this, propose to change the view to a list view which will show the hosts in a
list view with radio button. Additionally have a search option where the hostname can be searched
in this list to make it more usable.
