Task Description:

The clusters page lists counts of nodes and virtual machines, but it uses values taken from Cluster.instances() which always queries ganeti. Not only should querying ganeti be avoided, but it is causing inconsistency between counts when virtual machines were deleted from ganeti but not yet removed from the database.

This should be updated to use Cluster.virtual_machines.all().count()
