Prior to this patch, setting the CONF.debug to True in the ironic.conf
doesn't enable the debug logs in IPA. The user had to also append
"ipa-debug=1" to the CONF.pxe.pxe_append_params configuration option.
This patch is changing this behavior by making the CONF.debug option
reflect on the IPA logs as well. As I understand, IPA is just an
extension of the Ironic code that runs in-band on the node allowing
Ironic to access the local hardware. This way, in order to enable debug
as a whole the user only needs to set one configuration option.
The code in this patch checks if CONF.debug is set to True and also
check if "ipa-debug" is not explicit set in CONF.pxe.pxe_append_params
configuration - to not overwrite the user configuration - and only then
will append "ipa-debug=1" to it.
The "ipa-debug=1" kernel parameter was also removed from the devstack
lib because CONF.debug is always set to True there.
