Subject: [PATCH] Add track-by for updating hz-resource-table

hz-resource-table needs track-by attribute for refreshing rows.
And the identifier for track-by in each items needs timestamp
(created_at, updated_at or somthing) to detect difference
between old and new records.

This patch adds track-by attribute for hz-resource-table tag,
and set ID and timestamp into trackBy attribute for each items.
