Code Issues Proposed changes

Display host chosen for instance by scheduler 

The scheduler is configured to schedule an instance on a host chosen
randomly from a subset of the N best hosts. Where the size of the subset
is defined as 'scheduler_host_subset_size' from the configuration.

In a configuration where the subset is greater than the default (1) the
scheduler does not display where it has scheduled the instance to. It
gives a list of all those that it has weighed - just not the one chosen.

This patch displays the chosen host.
