Start using in-band inspection with ironic-discoverd, but do not instantiate the driver interface when discoverd support is disabled in the config file. * Check the CONF option prior to instantiating DiscoverdInspect class and binding it to any driver interface * Updates unit tests to better test the loading (or lack thereof) of the driver.inspect interface, based on the CONF option If in-band discovery is enabled by setting [discoverd] enabled=True in the config file, then the following drivers will bind it to their inspect interface: * pxe_ssh * pxe_ipmitool * pxe_ipminative * pxe_drac This patch also fixes a few nits (copied from previous reviews). The bug tagged below presently affects only the "fake" driver. Without the above-mentioned changes, enabling discoverd for any production-facing driver would have led to the problem described there. Updated UnsupportedDriverExtension error message to suggest that the extension might be disabled.
