[openstack-dev] [Ironic] Manual scheduling nodes in maintenance mode

I wanted to throw out an idea that came to me while I was working on
diagnosing some hardware issues in the Tripleo CD rack at the sprint last

Specifically, if a particular node has been dropped from automatic
scheduling by the operator, I think it would be super useful to be able to
still manually schedule the node. Examples might be that someone is
diagnosing a hardware issue and wants to boot an image that has all their
favourite diagnostic tools in it, or they might be booting an image they
use for updating firmwares, etc (frankly, just being able to boot a
generic, unmodified host OS on a node can be super useful if you're trying
to crash cart the machine for something hardware related).

Any thoughts? :)
