While the traditional domain configuration file format works acceptably,
I can see uses for having full JSON support.  As such add "-j" and "-J"
to `xl create` to specify format.  The traditional format is the current
default.

While attempting this, it came up that options for `xl create` aren't in
a consistent order.  I'm concerned about moving the VNC options apart,
but the others have been sorted.

Due to one issue in the previous round I ended up examing the dom_info
variable in main_create().  The situation there is a bit tangled.  There
were shadow variables for everything in dom_info.  Unfortunately the
short-hand serves to confuse, so I believe the appropriate action is to
remove the shadows.  Appears .dry_run had effectively been deprecated,
but not fully removed; as such now fully remove it.

Rename everything "format" to "config_format".
