Open Stack

Hi, folks.

I understand it may be not a good time but I want to make a proposal
regarding this feature.
The feature may be extremely useful for plugin developers if these labels
would be serialized into astute.yaml. They may be used by plugin tasks to
do node-specific modifications. Let me provide some examples:
* For Xen integration we need to provide unique Xen Server credentials for
each Compute node. But with current architecture we don't have any
customizable per-node parameters.
* It may be possible to use special labels to override global values (i.e.
libvirt_type, thus implementing BP
https://blueprints.launchpad.net/fuel/+spec/auto-virt-type).
* Another case may be the fencing. A user may put IPMI credentials into
labels.
And there are more cases like that.

Despite the original spec doesn't have this idea I propose to implement
that. Moreover, I've already did it. Here are my two commits with a spec
update [0] and an implementation[1]. They are pretty simple.

Please grant FFE to this feature with my additions till tomorrow evening.
