Unfortunately the value to set for stickiness is some what balck magic:
It seems it does not make a real difference whether you set it to 5, 10, 100,
or 1000; once grater than 0 it prevents resource migration, even when a
placement strategy suggests that the placement is non-optimal (e.g. after a
node restart).
