Refactor FDB Tables to Laravel (#9669)

* Refactor FDB Tables to Laravel
Hopefully much better performance with large tables.
Better dns resolution (limit to 4 IPs tried per MAC)

* update style

* de-duplicate IPs

* fixed column width for mac and vlan

* Make DNS column visibility control whether or not we send the dns query.
Hide that column by default.
