Brian Haley 955fa1c075 Implement 'get-me-a-network' API building block
This patch introduces an API to allocate an externally connected
private tenant network on demand. The API is idempotent in that,
once the topology is provisioned, further API calls keep returning
the same topology to the caller.

The API, as introduced by the patch, is not currently on, and its
design carefully ensures minimal impact on the existing codebase.
In fact the feature depends on and enhances the external-net extension,
but it does so via callbacks.

A subsequent patch in this series will make it available by default,
and API tests will be added to validate the functionality.

Partially-implements: blueprint get-me-a-network
