Change (*nftables.Table).Apply() to take an arbitrary number of
Modifiers to be applied as a single atomic unit. Having the ability to
atomically apply multiple modifiers to a table enables some powerful
patterns such as atomically replacing one collection of rules or
elements with another:
var update nftables.Modifier
update.Create(/* ... */)
t.Apply(reversePrevious, update)
reversePrevious = update.Reverse()
