Subject: [PATCH] -i libvirt: print URI without connecting (RHBZ#1839917)
Pass (again) around the libvirt URI string in the various input_libvirt
subclasses so that input_libvirt#as_options does not need to connect to
print the connection URI.
As related change: pass input_conn as non-optional string parameter in
classes that require one (all but input_libvirt_other, basically). This
avoids the need for extra checks.
(cherry picked from commit 86d87563ee03e86ca9abdcad4f674af66a883006)
