[Libosinfo] [PATCH] Add ability to list install script config params & profiles

[Daniel P. Berrange]

From: "Daniel P. Berrange" <berrange at redhat.com>

When using 'osinfo-install-script' it is useful to know what
profiles and config parameters are available. Add two new
flags --list-configs and --list-profiles to output this
information

 # osinfo-install-script --list-profiles win7
 desktop: autounattend.xml
 jeos: autounattend.xml

 # osinfo-install-script --list-config winxp
 admin-password: optional
 user-realname: required
 reg-product-key: required
