cloud scheduler needs to re-evaluate rules upon node status changes

[gemblerz]

The cloud scheduler will need to re-evaluate submitted jobs for re-distributing it to nodes based on node status

Example 1.
A new node is added to a project and there is a job that runs a plugins on all nodes under the project. The new node should also receive the job as it starts talking to the cloud scheduler.

Example 2.
When an node running for a job needs to be in maintenance the cloud scheduler removes (or do not consider) the node from the job.

Example 3. (?)
A user is removed from a project. The cloud scheduler may need to drop all jobs under the project, submitted by the user.
