Tune suggested master disk sizes for big clusters. 

Looks like the get-master-root-disk-size() and get-master-disk-size() functions didn't anticipate
clusters bigger than 2K nodes.

In https://github.com/kubernetes/kubernetes/issues/72976 we found out
that 100GB may be not enough for large clusters (5K nodes) when it comes
to master root disk size.

Updating both get-master-root-disk-size() and get-master-disk-size() to
make them consistent and match cluster sizes with get-master-size()
function.
