rashmidixit d8158fe5f4 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.
