fix tests

skip notimplemented error

remove factory unused

in openstack we should try to find instanceid from all states instead of ACTIVE, all other cloudproviders do this already

Jonathan Basseri 30b89d830b Move scheduler code out of plugin directory.
This moves plugin/pkg/scheduler to pkg/scheduler and
plugin/cmd/kube-scheduler to cmd/kube-scheduler.

Bulk of the work was done with gomvpkg, except for kube-scheduler main
package.

Walter Fender 9187b343e1 Split the NodeController into lifecycle and ipam pieces.
Prepatory work fpr removing cloud provider dependency from node
controller running in Kube Controller Manager. Splitting the node
controller into its two major pieces life-cycle and CIDR/IP
management. Both pieces currently need the the cloud system to do their work.
Removing lifecycles dependency on cloud will be fixed ina followup PR.

Moved node scheduler code to live with node lifecycle controller.
Got the IPAM/Lifecycle split completed. Still need to rename pieces.
Made changes to the utils and tests so they would be in the appropriate
package.
Moved the node based ipam code to nodeipam.
Made the relevant tests pass.
Moved common node controller util code to nodeutil.
Removed unneeded pod informer sync from node ipam controller.
Fixed linter issues.
Factored in  feedback from @gmarek.
Factored in feedback from @mtaufen.
Undoing unneeded change.
