[openstack-dev] [gantt[ Patches to sync gantt up to the current nova tree

Those patches are not a problem.  Once they are approved and pushed into the nova tree I will backport them over to gantt.  To re-iterate, the idea is to keep the current development going in nova and only when the gantt tree is functional and provides the same functionality as the scheduler inside the nova will we consider moving all development to gantt.

According to https://www.mail-archive.com/openstack-dev@lists.openstack.org/msg12973.html, it is said that we should not stop nova scheduler working for now.
BTW: I think that we may need to consider the following patches to enable Nova use scheduler from Oslo first to reduce future work before sync up to Gantt.

I suspect because gantt forked a while ago, but development has been
allowed to continue in nova's scheduler code. Seems like that should be
stopped at some point soon to reduce the extra sync effort.
