cli: improve bash completion by parsing options separately.
To support optimal completion, more context must be considered. Especially the OPTIONS, which must appear before the OBJECT. Modify bash completion to try parsing first the options. Before, whenever you had options, completion did not work anymore (because the object was expected as first argument). Moreover, options were also suggested after specifying the object. This is now mitigated by parsing the command line in two steps. Signed-off-by: Thomas Haller <thaller@redhat.com>
