Matt Riedemann 6ebee92445 Add cross-cell resize policy rule and enable in API
This adds the "compute:servers:resize:cross_cell" policy
rule which is now used in the API to determine if a resize
or cold migrate operation can be performed across cells.

The check in the API is based on:

- The policy check passing for the request.
- The minimum nova-compute service version being high
  enough across all cells to perform a cross-cell resize.

If either of those conditions fail a traditional same-cell
resize will be performed.

A docs stub is added here and will be fleshed out in an
upcoming patch.

Implements blueprint cross-cell-resize
