Prow: Use flavors with local disk

[lentzi90]

To improve performance and reduce the risk of network issues due to volumes mounted over network, we switch to flavors with local disk. Root volumes are no longer needed.

Fixes: #922

The changes are already applied. As you can see, the flavors are a bit bigger than what we used to have. If it turns out that we are wasting resources this way, we may ask for smaller flavors in the future. For now I think we can try this.

Agree, let's start with this and get the prow monitoring done, then we have data to make decisions.
