Create links between FWaaS resources

Part of blueprint fwaas-horizon

This commit creates cross links between FWaaS resources
and resolves FWaaS resource UUID in tables to its name.
This helps users to track FWaaS resources.

This commit also improves an error handling when an error occurs
during retrieving a resource detail via API call.
While previously a detail page without item values is displayed,
now the index page is displayed for such case.

Closes-Bug: #1229433
