[virt-tools-list] [PATCH virt-viewer] file: add delete-this-file option

[Marc-André Lureau]

In case the virt-viewer setting file is meant to temporary, you may use
the delete-this-file=1 option to ask the client to remove it, once it
has been read. This is useful for example in ovirt context, where
connection settings file are generated and can't be reused.
