List default Address pools row actions as disabled

Default address pools are read-only by design, any attempt to delete
 or update them will fail. Default address pools row actions dropdown
 menu has been disabled in order to prevent the unwanted behaviour.

Test Plan:
PASS: Go to Admin > System Configuration > Address Pools. Create one
custom Address pool, save changes and wait until the address pools
list is updated properly.
PASS: Go to Admin > System Configuration > Address Pools. Select and
update custom Address pool, save changes and wait until the address
pools list is updated properly.
PASS: Go to Admin > System Configuration > Address Pools. Select and
delete custom Address pool, wait until the address pools list is
updated properly.
PASS: Go to Admin > System Configuration > Address Pools. Try to
update default Address pool, actions is not allowed.
PASS: Go to Admin > System Configuration > Address Pools. Try to
delete default Address pool using dropdown option, actions is not
