Downgrade ipxe-qemu during grenade job
Temporary workaround while we find the problem with the
newer ipxe-qemu package.
Task: #26553
Switch grenade job to wsgi
Now that grenade is using Rocky as its base we
can switch to WSGI for ir-api. Also now required
for CI as IRONIC_USE_WSGI was getting flipflopped
from False -> True -> False during the grenade job.
Task: #26594
Disable the ironic-api redirect as it doesn't work with wsgi
Task: #26595
Increase the keystone token timeout, for grenade jobs only
Task: #26596
