mgmt/cli: adds globalId to AttachmentsList
mgmt/cli: adds globalId to AttachmentsList

Came from Cloudalize where some of the volumes are still named
with uuids, so searching for a globalId in this case could be
performed on the node where the attachment resides by
looking at symlinks in /dev/storpool-byid

Adds a fix for multicluster attach list indentation.
