Add more swap with loop dev

Browse Source 
In upstream, devstack-gate will ensure there is at least 8GB swap.
We can't actually set 8GB swap as there is no enough disk space.
And actually we have enough memory for CI jobs at the moment. So
let's make a thin file and use loop dev to make the swap. Even
it will use swap really, it should happend after we remove the
cached directory - /opt/git. So it won't be a problem at all.
