Host pools improvements

- Traffic Policy: get first available pool, not the "Not Assigned"
- Allow to change MAC address host pool from the MAC page
- When changing an IP address pool from the host page, change MAC address instead, if available
- Show the MAC manufacturer in the host pool memebers page and allow to set a filter with it
