[docs][userguide] Use literalinclude instead of duplicating the sample configs
This should reduce the inaccuracies, since the sample configs are easier to test, and changes don't have to be sychronised between documents. Change-Id: I92a1937ff0308df25ea3a345f2772027033f0302 Signed-off-by: Emma Foley <efoley@redhat.com>
