tests: Move the "ctdb reloadips" test from complex/ to simple/

This is made possible by separation of public addresses files for
local daemons and the addition of get_ctdbd_command_line_option().

+Verify that IPs can be rearrranged using 'ctdb reloadips'.

+
+Expected results:
+
+* When addresses are deconfigured "ctdb ip" no longer reports them and
