CLOUDSTACK-9020: Metrics views for CloudStack UI

Implements following:
- A metrics table widget that is:
  - vertically and horizontally scrollable with pagination/infinite scrolling
  - sortable columns (client side)
  - groupable/collapsible columns
  - alternate row coloring
  - refresh button to refresh views
  - threshold table cell coloring
  - panel/breadcrumb navigation
  - quick view action column
  - translatable labels
- Sortable column for all CloudStack tables (client side)
- Configurable UI pagesize for list API calls, 'default.ui.page.size'
- Metrics views: Zones, Clusters, Hosts, Instances, Storage pools, Volumes
- Resource filtering/navigation: Zones->Clusters->Hosts->Instances->Volumes, Storage Pool->Volumes
