Make relationships in objects consistent
In Volume object 1:n relationship on volume_attachment was modeled
by ListOfObjectsField. Moreover _from_db_object and obj_load_attr

In CGSnapshot similar relationship on snapshots was done by ObjectField
with SnapshotList inside.
This commit unifies the approach to use the latter. Also unit test is
added to prevent mismatch of field type and value set on it.

windows: don't use LOG.exception if not logging an exception

you're not in a logging handler context it fails. That bug is fixed
inadvertantly in python 3.5 under:
http://bugs.python.org/issue17911
This fixes the instance in the windows vhdutils module to use LOG.error
rather than LOG.exception to avoid that logging error.
Since LOG.exception was being used I'm assuming the original author wanted
traceback given this is a utility method, so we use the exc_info kwarg which

Function volume_types.get_all_types returns dict, then
VolumeTypeList.get_all passes it to base.obj_make_list, which, in turn,
passes it to oslo_versionedobjects.base.obj_make_list.
And this function iterates over 4th argument and calls
item_cls._from_db_object for each item. So if it will iterate over dict
from volume_types.get_all_types, it'll get strings instead of orm
objects.

Currently when LVM_SYSTEM_DIR is added to LVM.LVM_CMD_PREFIX it is
hardcoded as /etc/cinder.
However the configuration option lvm_conf_file could specify a file
located in an arbitrary directory, not just /etc/cinder, so we should
