Returns the distribution bits this cluster should use.
On Hosted Vespa this is hardcoded and not computed from the nodes because reducing the number of nodes is a common
operation, while reducing the number of distribution bits can lead to consistency problems.
This hardcoded value should work fine from 1-200 nodes. Those who have more will need to set this value
in config and not remove it again if they reduce the node count.
