libvirt: speed up list_instance_uuids method

Switch the list_instance_uuids method to use the new
list_instance_domains method.

Two tests related to list_instance_uuids were removed,
since the earlier tests for the list_instance_domains
method now capture those scenarios.

Update docs to highlight that the auditor chunk size can be set

May not be obvious, but existing code will let you change the
disk_chunk_size just for the auditor so this just points that
out in the docs.  In one short test I ran with a 4 node cluster
with 18GB of 4MB objects on it, changint he auditor chunk size
from the default of 64K to 1MB creased the auditor CPU time from
10% to 4%.

Also added test code to make sure this overridden value is
actually used and checked other auditWorker conf values as
well.
