Updated ironic.headers and ironic.flagmappings. I did this because
we renamed 'discoverd' to 'inspector' but these changes also reflect
additional changes in the configs from the master branch of ironic.
I edited ironic.headers and modified ironic.flagmappings (after it
was updated via './autohelp-wrapper update ironic'). The .xml files
were updated from running './autohelp-wrapper docbook ironic').
ch_baremetalconfigure.xml was edited to reflect the changed tables.
