Code Issues Proposed changes

Add a trait that compute manager can handle accelerator requests. 

When a Cyborg device profile name is present in the flavor, the
conductor will initiate creation and binding of accelerator requests,
and the compute manager must wait for the ARQ binding notifications.

In a deployment where the conductor is new, but one or more compute
managers are older than the needed version, this flow will break.
To prevent that: (a) the compute manager publishes this trait,
and (b) the scheduler factors this trait in the Placement query, so
that older compute nodes are not included in allocation candidates.
