Code review comment for lp:~vladimir.p/nova/admin-vm

Definitely not InstanceConfig :-)

I suppose the main purpose is to distinguish between regular compute
instances and administrative instances (instances created for other needs):
statistics/billing VMs, some special DBs, instances for hosting Virtual
Storage arrays/controllers, even VPN instances, etc. Most likely such
instances will have different configuration description / templates, but it
is probably a different question.

I'm open to any suggestions, but for me InstanceType or InstanceCategory are
winners... meanwhile :-)
