Francesco Romani 6dcec345df smtalign: cm: factor out admission response
Introduce a new `admission` subpackage to factor out the responsability
to create `PodAdmitResult` objects. This enables resource manager
to report specific errors in Allocate() and to bubble up them
in the relevant fields of the `PodAdmitResult`.

To demonstrate the approach we refactor TopologyAffinityError as a
proper error.
